An Android file manager is an app that lets you explore the files on your Android device, similar to the Windows File Explorer or macOS Finder. WIthout an Android file explorer, moving, copying, and pasting files on your Android device is much more difficult. 

Furthermore, many Android file explorers give you extra file management options, such as creating file archives, uninstalling apps, managing your SD card, cloud storage support, and more.

Check out the five best file managers for Android.

Solid Explorer has risen through the ranks of Android file explorer apps and is now one of the best options for managing files on your Android device.

It features a swish, streamlined user interface with easy to use menus, plus a range of themes to suit your color preferences, all using Google’s Material UI design. 

One of Solid Explorer’s best features is its side-by-side view, which allows you to drag and drop files or folders from one panel to another. The side-by-side view makes transferring files incredibly simple, saving you from having to remember where the destination folder is.

Aside from side-by-side file dragging, Solid Explorer also includes a powerful archive tool that you can use for creating and managing archives (such as a .zip or .7zip file), an option to stream your media files via the Chromecast integration, and a handy file encryption tool.

Solid Explorer is a premium file manager for Android. You receive a two-week trial, after which you’ll need to pay $2 to continue using the app.

Total Commander is one of the original Android file management tools. It offers an extensive and powerful collection of file management options for Android devices. 

Total Commander’s functionality can extend further using plugins, too. If you want to upload files to an FTP server, there is a plugin for that. If you’re going to use Wi-Fi direct file transfer, there is a plugin for that. You’ll also find Total Commander plugins that open Microsoft Installer Files, read and create ISO image files, provide an MD5 or SHA1 file hash, and so much more.

Some users will find the aging interface style a downside. But once you learn how to navigate Total Commander’s various menus, you’ll understand why many consider Total Commander the best file manager for Android.

If you don’t need the extensive functionality of Solid Explorer or Total Commander, you should consider the Simple File Manager. Unlike the other options on this list, Simple File Manager is a lightweight Android file manager meant for basic use.

That said, Simple File Manager is more than capable. You can rename, copy, move, delete, and manage your Android files. You can use Simple File Manager to check file properties or to create home screen shortcuts to specific files.

Furthermore, Simple File Manager includes some extra security functions, too. For example, you can use Simple File Manager to password protect and hide special files or folders, or lock a specific folder using a fingerprint scanner.

Aside from security and file management, Simple File Manager has several options for customization, including color schemes and themes.

MiXplorer is a file manager for Android that flies under the radar. A favorite of XDA Labs, the Android developer’s forum, MiXplorer is one of the most feature-packed Android file management apps available. Better still, it’s entirely free.

Furthermore, MiXplorer includes options for the creation and management of archives, encryption tools, a basic text editor and image viewer, and more.

The excellent free version of MiXplorer is available as an APK, which means you must sideload the installation file onto your Android device. Check out how to install apps on your Android device from your computer for more information. 

There is also the MiXplorer Silver app available on the Google Play store, at the cost of $5. MiXplorer Silver bundles the MiXplorer file manager with several other apps from the developer and, of course, supports the developer financially.

Astro File Manager is one of the oldest and most popular free Android file manager apps. One of the best Astro File Manager features is the integrated cleaner. You can use Astro File Manager to help keep on top of your Android device spring cleaning, making sure you never run out of storage at a critical moment.

Astro File Manager isn’t flashy or brimming full of features and plugins. But it is a solid file manager for Android, which is what keeps it at the top of the Android file management app rankings.

Here in this article we will discuss what’s different in Apple’s latest smartwatch and should you upgrade your Apple Watch?

So, what are you waiting for? Let’s read further to know more about Apple Watch Series 5 and what it’s worth.

What is Apple Watch Series 5?

Although the series 5 watch comes with the same dimensions as the older Apple Watches i.e. 44 mm and 40 mm sizes, touchscreen, a heart rate tracker, optional GPS, and cellular capabilities. Still, it stands out as no longer you’ll need to lower your wrist to turn the display off or on.

In addition to this, users get a built-in compass that can be used during hiking, running or doing other outdoor activities. For me, this new addition is enough reason to upgrade.

Isn’t all this great or you want to know more?

To know more let’s read further.

What makes Apple Watch 5 different?

Apple at its annual event clearly showed that the company will not give incremental updates. Instead, the company will offer, the new generation of Apple Watch with new and unique features that older models missed.

For Apple Watch 5 the biggest selling point is the always-on screen, without battery drain. This surely will entice those who are thinking about an upgrade. Moreover, a suite of apps, emergency dialing all are also great add-ons.

Specification of Apple Watch Series 5

Despite the fact that the company intentionally neglected to mention any hardware specs during the event. There are a few major differences between Series 4 and Series 5.

Apple Watch Series 5 has the latest series of processors.

It has an always-on display.

Additional storage space and a compass sensor.

Beyond this, you can say fifth-generation Apple Watch is similar to Apple Watch Series 4.

Apple Watch Series 5’s biggest competitors?

The other 60% of the market is taken over by companies like Samsung, Fossil, Fitbit, and others. Alongside Emporio Armani is also stepping into the market of smartwatches.

Do you see any similarities here? Yes, you guessed it right it’s similar to the market share of iOS and Android.

iOS somewhere has a 40% share whereas Android has a major share with 60%.

Smartwatches, for now, are considered to be an extension of their parent OS. Where Google offers an app to allow Wear OS devices to work with iOS, Apple offers no such app for Android, so if you have an Apple Watch it means the only choice you have is of Apple’s ecosystem.

Should Professionals care about the Apple Watch Series 5?

For professionals, the only thing that could make a difference is the always-on screen. This feature will make it easy to see the time, upcoming appointments, meetings, weather and a lot more without tapping the screen or lifting the wrist. Alongside if you are a traveler or work outdoors then the secondary features will also appeal to you.

A compass will make navigation easy for travelers. Alongside they will have instant access to local emergency services.

In a nutshell, we can say if any of the Apple Watch Series 5 features piqued your interest, it is worth upgrading. However, if none of them seem beneficial and you are okay turning on the display each time you can skip the upgrade for now.

Cost of Apple Watch Series 5

The Apple Watch Series 5 starts at $399 USD for a GPS-only model and $499 USD for a cellular model.

How always-on feature works in Apple Watch 5?

Similar to other smartwatches, especially last year’s Qualcomm Snapdragon 3100 Wear OS watches, the always-on display works only when the watch is on the wrist.

We can say that although, Apple Watch Series 5 doesn’t feel very different when compared with older versions, yet it’s always-on display and other secondary features are a big change we are glad to welcome.

Top 5 Techniques In Javascript For Google Tag Manager

Do you want to step up your measuring game? 

If you’re using Google Tag Manager, learning how to use JavaScript, the programming language GTM is built on, will without a doubt help you achieve your GTM success goals.

These are the top 5 must-know techniques for Google Tag Manager:

1. Data Layer

Let’s start with a straightforward but powerful command to access the Data Layer.

A website typically has three layers: the presentation layer – what your users see, the applications layer – made up of tools connected to the website (e.g. Google Analytics and Google Tag Manager), and the Data Layer – where user-generated data gets stored.

The Data Layer provides a reliable way of collecting data from your website. The values inside this layer are often used by Google Tag Manager to pass information to your tags.

These include events, variables, and triggers that can be set up based on the variables’ values.

If you or your developer placed the Google Tag Manager container JavaScript snippet (gtm.js) in your website’s source code, then the Data Layer is automatically created.

Let’s say a friend sends you their website and wants you to check if their tracking is working. Since the Data Layer is the basis of GTM, the first step to checking their tracking deployment should be to look at the Data Layer. 

A quick and convenient way to access the Data Layer, even without having access to the Tag Assistant, is to go to your browser’s Developer Tools. 

If you’re using Google Chrome, go to the applications menu → More Tools → Developer Tools.

The developer tools for other browsers should be in a similar location. You can also use the keyboard shortcut Ctrl+Shift+I for Windows or Cmd+Shift+I for Mac.

In the Console tab, type in dataLayer, then press Enter.

🚨 Note: JavaScript is a case-sensitive language. The dataLayer command should be entered with a small letter d, capital L, and with no spaces to properly access the Data Layer.

To see the updated Data Layer information, we need to input the dataLayer command again. Here, we can see that there are now 7 items in the Data Layer, which includes the add-to-cart event.

💡 Top Tip: Pressing the up arrow key will copy the latest command you have typed in the JavaScript console.

Your troubleshooting can end here since you see that the Data Layer is set up properly or you can proceed and check other events.

If you need a quick way to check the Data Layer without extensions like the Tag Assistant, just type in the dataLayer command to your JavaScript console. 

2. Data Layer Push

The next command attached to the Data Layer is dataLayer.push, which is used to store data in the Data Layer. This command uses an object with a key and value pair as an argument.

To check how it works, type in the following Google Tag Manager code example:


Press Enter. This should then return true.

If we invoke the dataLayer command again, we will see the key-value pair as the latest object in our Data Layer that we can then use in our tracking.

Now, when would it be useful to know a command like this? If you want to build a Data Layer and push custom information to it, then this command is something you need to learn how to use.

This command can be perfect if you only want to try out your tracking, and if you already have built tags that listen to a certain Data Layer event.

For example, the chúng tôi command can send in a purchase event by invoking the next GTM code example:


You can then view the purchase event in the Tag Assistant, as well as the information that was brought in.

Inputting your chúng tôi codes in the JavaScript console allows you to try them out beforehand and check if they are working properly before you implement them on your tags.

For example, if you wanted to install the enhanced eCommerce purchase tracking from the developers’ page, you can first try it out by copying the code and pasting it to the JavaScript console. 

You can then see how this code affects the Data Layer based on the message you get. 

Since this code returned true, it means it is working properly and will work fine when implemented in your tags.

However, if you try out another piece of code and it returns an unexpected error, it means something is not right in your code.

Knowing that there is an error beforehand allows you to correct your mistake before you send it to your developer and implement it on your website.

To fix this error, we simply need to go into the code again and put in a comma at the end of the affected line.

We’ll know if the code has been fixed if it returned true.

It is very handy to know about the chúng tôi functionality to design your Data Layers, try out Data Layer syntax, and find errors, before you give it over to a developer and implement it on your website.

After pushing data/events to the Data Layer, you can then use the Data Layer event as a trigger and use the data to create your tags or variables.

🚨 Note: Check out our guide on scraping data with Chrome developer tools and GTM to learn how to inspect a website element and copy its JS path to create a GTM custom JavaScript variable.

3. Query Selector Method

The next technique we can use to utilize JavaScript for Google Tag Manager is the query selector method.

We have already discussed how you can pull data from and push data to the Data Layer, but what if the data you need for your tracking implementation is not in the Data Layer?

This method is very important for Google Tag Manager because it lets us select some aspects of the page that are present in the presentation layer. 

The presentation layer is made up of elements on the page that the user sees, and is built on HTML and CSS. To proceed with this method, you do need to have some background in CSS so that you know how to select an element.

As we’re trying to keep this discussion as digestible as possible, knowing how CSS selectors work will help you better utilize the selector method for your website and meet your specific tracking needs.

This opens the developer tools on the elements tab where the HTML tag containing the inspected element is highlighted. Take note of the parent elements from the highlighted tag.

What the query selector does is that it finds an element on the page and returns it to you, so that you can do further operations on it and transfer it over to Google Tag Manager.

Let’s now utilize the query selector command and test how the CSS selector works. To start, let’s pull the elements that have the price class. We need to use the class selector inside the query selector command with the syntax ‘.classname.’

Type the following code in the console tab, making sure that the CSS selector is enclosed in parenthesis and single quotation marks:


Press Enter. If we hover over the HTML element that the command returned, the equivalent element on the webpage will be highlighted.

This is a good start since the correct area is highlighted. However, aside from the price, other things are also included. Therefore, we need to dive deeper and be more specific about the CSS selector we use.

Our command should now be:

document.querySelector(‘.price span bdi’)

Checking and hovering over the element returned from using the command now only highlights the price with the dollar sign.

We can then only pull out the text inside the HTML element by adding .textContent at the end.

After testing it and knowing what it selects, we can then now use this CSS selector in different places inside GTM.

Let’s go over to Google Tag Manager and build something that will pull out that text exactly. For example, we can go and create a DOM element variable.

Go to Variables → New.

A DOM element variable has two options for the selection method: ID or CSS Selector. The one we are interested in is the CSS selector option since our HTML tag does not have an ID attribute.

Select CSS Selector for the selection method, then paste the CSS Selector we used inside the querySelector command.

We can also use the query selector method to create a custom trigger. 

Head over to Triggers → New.

We’ll be creating an element visibility trigger. This trigger fires when a selected element becomes visible in the web browser’s viewport. 

Like the DOM element variable, we’ll select CSS Selector for the selection method, and then paste the CSS Selector we used inside the querySelector command.

💡 Top Tip: Always test your CSS selectors before using them in your variables, triggers, or tags. Use the query selector method inside your browser’s developer tools to ensure that it returns your desired results

4. Google Tag Manager Object

Next up, we have the Google Tag Manager object.

This is especially useful when you are looking again at the Data Layer. The dataLayer command we utilized earlier gives you access to the Data Layer, but not the internal model of Google Tag Manager. This is an object on the page itself.

Google Tag Manager has an internal representation of the Data Layer that can be different from the tags and variables we define.

When you want to access the internal data model of Google Tag Manager, you will first need to know your GTM container ID, which you can locate at the top of your GTM homepage.

The command syntax we will use to invoke the GTM object command is:


When you type out the command in the console tab of your browser’s developer tools, your container ID can also pop up as a suggestion.

💡 Top Tip: Press the right arrow key to autofill your container ID without typing it or selecting it from the list.

The things you can do with the GTM object command are multifold, but what we have found is especially useful for looking at the Data Layer. 

We can then use the get command to fill in anything that we would usually put into our Data Layer variable. What you usually put inside the data layer variable name can also be used inside the GTM object.

To illustrate how you can pull data from the Data Layer using the GTM object command, let’s go into the Tag Assistant → Data Layer and see what kind of elements we have. 

For this example, let’s look at the ecommerce.currencyCode.

We would normally build a Data Layer variable out of this and go into the Tag Assistant and check if it’s working properly there. However, with the GTM object command, we can easily test it out without building the variable.

The command syntax should now be:


Type this in the console tab, then press Enter. It should then return the corresponding value for our key as what was written in the internal data model.

Aside from testing Data Layer variables beforehand, we can also use this as an alternative to creating the variable altogether. Let’s see how this comes in handy by looking at an example.

In this GTM account, we have three types of variables: custom JavaScript, Data Layer variable, and DOM element.

If we look inside our Google Tag Manager custom JavaScript variable, we can see that we are utilizing the data layer variable in the code.

Instead of going through the additional step of creating a Data Layer variable to pull data from the Data Layer, we can simply use the GTM object command and pull data directly from the custom JavaScript variable.

To do this, first, go into the Data Layer variable and copy the contents from the Data Layer Variable Name field.

Before proceeding, make sure you have the built-in container ID variable enabled. 

Here, you can find the Container ID under Utilities. Check it if you haven’t already.

We can then go inside the custom JavaScript variable and replace the Data Layer variable with the GTM object syntax we used earlier.

Instead of putting in our actual GTM container ID, we will use the container ID variable. The key we’ll use is what was inside the Data Layer Variable Name. This should work in the same way.

Now you might think that is this pretty much just a longer version of what we put in earlier and wonder what’s the point of all of this. By using the GTM object, there is no need to create multiple variables just to pull specific data from the Data Layer.

This is especially useful when you want to quickly pull and use data from the Data Layer in a single tag or variable. It might be easier to write out the relatively lengthier GTM object command and it won’t take as much space inside your GTM account.

That is how you implement the GTM object inside the variable. You can also utilize the same method inside your tags.

Using the GTM object command in the console tab will make your life easier because you can quickly check something and see how it’s resolved without having to create a Data Layer variable.

There are several other methods for how you can utilize the GTM object and one we want to highlight is how you can transform the Data Layer whenever the Data Layer provides the right information, but not in a format you could use.

5. Immediately Invoked Function Expression

The last technique for utilizing JavaScript for Google Tag Manager is the Immediately Invoked Function Expression (IIFE).

Where can this be useful and why should you use it? After going through the other JavaScript techniques in this guide, you may have noticed that we use certain keywords in the console tab that you have to remember to access specific things like the Data Layer.

These are reserved keywords that are hopefully not being used by any other programmer or script. When you have many different scripts running on your page, all of them are competing for the same space. Ideally, you should use unique variable names throughout.

Whatever command we have used in the console tab access data from the global scope. If you’ve used some reserved keywords in your tags, then you are effectively overwriting them.

For example, if we use the dataLayer command on a different website, it returns Hello instead of all the items we expect to see from the example earlier.

This happens because we have a custom HTML tag where we used JavaScript to overwrite the Data Layer.

🚨 Note: As much as possible, try to avoid using dataLayer or any other reserved keyword to name any of your variables.

If you have lengthy codes or haven’t written the code and copied it from somebody else, then ensuring that all your variables are using unique names can quickly become tedious and time-consuming. 

A quick way to remedy this is by utilizing an immediately invoked function expression. 

IIFEs are functions that are executed immediately after being defined. This creates a context for your code to run in that is closed off from the global variable space, eliminating the danger of overwriting anything from the global scope.

Simply place your code inside this snippet to use the IFFE:

(function () { })();

Going back to our example, your code should look similar to this:

If we go back to the developer tools, trying out the dataLayer command should now return the snippet we expect to see, because our custom JavaScript is running in a completely different context.

💡 Top Tip: Always implement an immediately invoked function expression whenever you run a custom HTML code in your tags to avoid future conflicts.

FAQ What is the Data Layer Push technique?

The Data Layer Push technique is used to store data in the Data Layer. It involves using the “dataLayer.push()” command with an object containing a key-value pair as an argument. This allows you to push custom information to the Data Layer and test tracking before implementing it in tags.

How can I use the Query Selector Method in Google Tag Manager?

The Query Selector Method is used to select specific elements on a webpage that are not in the Data Layer. It involves using CSS selectors to identify and retrieve elements from the presentation layer of the website. This method is useful for pulling data from elements on the page that the user sees.

What is the Immediately-Invoked Function Expression (IIFE)?

The Immediately-Invoked Function Expression (IIFE) is a JavaScript function that is executed immediately after it is defined. In the context of Google Tag Manager, it can be used to encapsulate and execute code within a function to ensure proper scoping and avoid conflicts with other scripts on the page.

5 Best Racing Apps For Android For All Types Of Racing

Price: Free / Varies

Formula One is one of the most popular racing leagues on the planet. Thankfully, the organization takes mobile at least somewhat seriously. You get a few different racing apps from Formula One. That includes a general live streaming and news app. The live streaming requires a subscription, but the news part is free. There is also a live timing app for those who want the hardcore stats and metrics. All of the apps work pretty well and subscriptions are available in many regions around the world. The prices vary by region, so you’ll have to check and see what the app charges for you. The F1 TV app even added Android TV support in late 2023.


Price: Free / $5.50

Freader1 is one of the few really good racing news apps. It covers Formula One news mostly. You can view things like race results, upcoming races, racers, and other types of car news. There are also video highlights and news stories as well. It rounds out the experience with race reminders, a calendar with the full schedule on it, and a light and dark mode for easier day time and night time reading. The UI could be a little cleaner and more modern, but that’s really our only complaint and it’s not a very big one. This is arguably the best news app for Formula One racing fans.


Price: Free

NASCAR Mobile is the official app of NASCAR. NASCAR and Formula One have a bit of a rivalry, but NASCAR is extremely popular in its own right. The official app has the kinds of things you would expect. That includes news, video highlights, a racing schedule, leaderboards, stats, and other such things. It’s a good first step for fans of the sport. However, it doesn’t offer much in the way of video streaming. Most races are broadcast on Fox, Fox Sports, and NBC Sports. We recommend a good live TV app like Sling TV, YouTube TV, DirecTV Now, or something similar to actually watch NASCAR. We have our list of the best live TV apps listed just below the first paragraph of the article!

Individual racing league apps and sites

Price: Free (usually)

There are a bunch of individual, independent, and smaller racing organizations. There are really only three ways to follow those smaller organizations. That includes social media, the official websites, and (when available), official apps. It’s hit-or-miss for basically all of them. We found an official app for USAC Racing, but not one for the NHRA. However, everything has an official site and also an official social media presence. We recommend booting up your favorite browser or social app and finding them there.

Joe Hindy / Android Authority

Most sports news apps

Price: Free (usually)

Most sports news apps cover racing to some extent. They usually only cover the big dogs like NASCAR and Formula One. However, considering that those are the most popular racing leagues, it’s not a super huge deal. Some ideas for you include theScore, ESPN, and Yahoo Sports. There are plenty of others. This is also a good option for those who enjoy other sports aside from racing. Most apps work well enough, although they may not have all of the in-depth news of an official source. We have our list of the best sports news apps linked at the button above if you want to see our list of those.

Ibm Watson’s Ancestors: A Look At Supercomputers Of The Past

On Monday, the epic three-night Jeopardy battle begins when IBM’s supercomputer Watson will take on the game show’s two greatest champions, Ken Jennings and Brad Rutter. On the line is a $1 million prize, and the pride of both human contestants as well as IBM’s reputation as a pioneer in machine learning.

It’s anybody’s guess who will win tonight, but in honor of what may be Watson’s intellectual triumph over humanity, here is a look at the rise of the supercomputer in human history.


Watson is based on IBM’s Deep QA project, which is attempting to create computers that can mimic the human ability to comprehend and answer natural language questions. The computer features 15 terabytes of RAM and about 2880 processor cores, can perform 80 trillion operations a second, and is the size of ten refrigerators.

Watson is seen as a giant leap forward in artificial intelligence because to play Jeopardy it had to understand and answer English language questions using idioms and common expressions. This is unlike previous computers, which required specific input keywords before they could respond to human speech.

Colossus Machine

Colossus was the first large-scale electronic programmable computer and was built by the British in 1944 during World War II. Colossus was designed to help Allied forces decrypt messages encoded with the Lorenz cipher sent from German High Command to Nazi officers in the field.

The machine was powered by about 1500 vacuum tubes, received input from paper tape, and sent its output to a typewriter. It took about six hours for Colossus to decrypt a ciphered message, according to a BBC report. A total of ten Colossus machines were built during the war.


The machine cost nearly $9 million and could perform (at top speed) 160 megaflops (160 million operations per second). It conducted these operations with 8 MB of memory.

Deep Blue

Perhaps one of the most legendary supercomputers of all time, IBM’s Deep Blue was developed specifically to test a computer’s capabilities to play chess. The machine featured 30 120MHz processors and performed at 1 teraflop (1 trillion operations per second). This version of the machine played a rematch with world chess champion Gary Kasparov after losing to the champ in 1996 by 4 matches to 2.

Columbia Supercomputer

NASA’s Columbia supercomputer was a collaboration between Silicon Graphics International, NASA, and Intel in 2004.

The system, housed at NASA’s Ames Research Center in Mountain View, California, features 10,240 Intel Itanium 2 processors and 27 terabytes of RAM. Columbia uses SUSE Linux Enterprise as its OS. The machine was designed to help NASA construct large-scale environmental models such as hurricane track prediction and global ocean circulation. Columbia also helps analyze the physics of supernova detonations and other large events occurring in outer space.

NASA says the first super computer at Ames could do 1 billion calculations per second. Columbia is 50,000 times faster than that.

The Jeopardy-IBM challenge lasts three nights, running from February 14 through 16.
