Suggested April 2024 Deleting Files On A Mac – Empty Trash Or Secure Empty Trash?

Deleting files in Mac OS isn’t a difficult thing to do by any means, yet it can be confusing. Everyone knows how to drag files into the trash can in the dock, yet to actually delete them, there are two choices in the Finder Menu – Empty Trash and Secure Empty Trash. Which one should you use? Is there a difference?

To understand which trash option you should choose takes a basic understanding of how files are stored on the Mac. Files are stored in chunks throughout the hard drive. Many times people delete files simply to free up more space on the hard drive. It improves performance, because if you’re running out of room, the files sometimes need to be saved in pieces just to get it to fit. Even if the files are sitting in the trash can, they’re still occupying those chunks of your hard drive; just moving them into the trash can doesn’t free up space at all.

If you choose the “Empty Trash” option, the files still don’t really go anywhere. They’re just hidden from view. What you are really doing is telling the Mac that if it needs free space to save a file, it can write over those files that were deleted before. The benefit of this is that if you change your mind and want the file back, you can use a file recovery program to get it back. However, if it’s been too long or you’ve saved too many things since you deleted it, it maybe have already been written over.

If you choose to “Secure Empty Trash,” there is no backing out. This option completely erases those chunks off your hard drive. No file recovery program will be able to get it back for you. However, it’s a great option for keeping sensitive information private. If you delete something you don’t want others to see, or if you are changing ownership of the computer, it’s a good idea to to completely wipe the hard drive, and to follow it with “Secure Empty Trash.” Either option you choose will still ask you if you are sure you want to empty the trash, just as a safeguard.

Knowing how the file system works, as well as the process of deleting files in the trash, can greatly improve the way you use your Mac. It will lead to less lost data, as well as more security for sensitive data.

How To Quickly Empty The Trash In Macos Using Terminal

However, permanently getting rid of the contents within the Trash isn’t always that easy and may result in errors. So if you run into any trouble, you can quickly empty the Trash in macOS using Terminal instead. You’ll find the complete procedure below.

Table of Contents

Delete the Trash in Mac Using Terminal (macOS El Capitan and Later)

If you use a Mac running macOS 10.11 El Capitan or later (such as Big Sur or Monterey), you can quickly empty the Trash using Terminal.

2. Type the following command:

sudo rm -r

Note: Do not run the command yet.

3. Press the Space key once to add a single space to the end of the command. It’s essential to do that. If not, the command will fail.

4. Open the Trash.

5. Select the files you want to delete while holding down the Command key. If you want to remove everything, press Command + A to highlight all files and folders instantly.

6. Drag the highlighted files into the Trash. Depending on how many items you want to delete, multiple file paths may show up in Terminal.

7. Press Enter.

8. Type in your administrator password.

9. Press Enter. Terminal will delete the specified items from the Trash. You won’t receive a confirmation, so it’s best to double-check.

If Terminal fails to delete a specific file or files, adding the f (force) option will override issues caused by conflicting permissions. Type sudo rm -rf in step 2. 

Emptying the Trash permanently deletes the files (unless you’ve set up Time Machine on your Mac). Hence, if you prefer confirmation before deleting each time, you can use the i (interactive) option—e.g., sudo rm -ri.

Delete the Trash in Mac Using Terminal (macOS Yosemite and Earlier)

On a Mac running macOS 10.10 Yosemite or earlier, emptying the Trash using Terminal is relatively uncomplicated. 

2. Type the following command:

sudo rm -rf ~/.Trash/*

3. Press Enter.

4. Type in your administrator password.

5. Press Enter.

Alternative Ways to Delete Problematic Files in Trash

Deleting the Trash using Terminal is quick. But it’s also inconvenient. If you can’t empty the Trash using the GUI (graphical user interface) in macOS due to a specific file or files, run through the pointers below the next time.

Delete Items Individually Unlock Files and Check Permissions

While you’re at it, you may also want to scroll down to the Sharing & Permissions section and set Privilege to Read & Write for your user account. You may not be able to do that if you don’t have administrative privileges.

Force-Quit Relevant Programs

Additionally, you might want to check if the relevant program is stuck. To do that, open the Apple menu and select Force-quit. If the program appears within the list, select the item and choose Force Quit. Here are other ways to force-quit apps in macOS.

Restart Your Mac

Restarting your Mac can also help resolve bugs, glitches, and conflicts preventing you from emptying the Trash.

Just open the Apple menu and select Restart. Then, leave the box next to Reopen windows when logging back in unchecked and choose Restart.

Disable Conflicting Startup Programs

If you continue to have trouble emptying the Trash normally, you probably have a conflicting program that boots alongside macOS. 

Booting your Mac in Safe Mode can also help you identify problematic or sketchy startup programs and extensions that cause issues.

Take Out the Trash

Despite being able to empty the Trash using Terminal in macOS, it’s best to stick to the graphical user interface, if possible. Taking the time to figure out what prevents you from deleting files within Mac’s Trash rather than force-deleting its contents may help you avoid having to deal with the same problem going forward.

That being said, if you end up permanently removing files and folders you later want to recover, don’t forget to restore the lost items using Time Machine.

Printer Printing Blank Or Empty Pages In Windows 11/10

When your home printer fails to work correctly, it can be a frustrating experience, especially when you have no idea how to solve the problem. One of the most annoying issues many have faced over the years is their printer’s inability to stop printing blank pages.

Why does my printer just keep printing blank pages?

Your printer may keep printing blank pages if the print head is clogged and the cartridge is not installed properly. It can also happen if printer settings are not correct or there is a low ink. A defective cartridge can also be the reason that your printer is printing blank pages.

Printer printing blank pages but has ink

For those who are unaware of what that means, well, it is when the printer performs an action, but when the page comes out, it is empty, or better yet, blank.

Now, we know that a printer printing blank pages is a common problem that has affected thousands of Windows 11/10 users. Still, it is not always easy to pinpoint the exact cause. With this in mind, we are going to explain how to set things right again, with multiple fixes as mentioned below:

Restart the printer

Check if your ink level is low

Clean clogged print head

Check Printing Preferences

Run Printer Troubleshooter

Align the print cartridge

Let us talk about this from a more detailed perspective.

1] Restart the printer

In most cases, the user only needs to turn off and turn on their printer to solve the problem. Do this by tapping the power button on the device to turn it off. Once that is done, remove the power supply cable, then wait for around 10-seconds.

Finally, reattached the power cable, then turn on the printer. Go on ahead and attempt to print a document to see if it now works.

2] Check if your ink level is low

Your printer may be shooting blanks because your ink levels are low. We suggest reading your printer manual to find out how to check the amount of ink sitting around in the cartridge. If it does not have a sufficient amount, then the chances are that is the reason for blank pages. So check your Ink or Toner cartridges.

The best option would be to purchase new cartridges or refill the ones you already have. The latter is cheaper but not always better.

3] Clean clogged print head

In a situation where you haven’t used the printer for an extended period of time, the print head could become clogged. We do not know of any manual ways to unclog a print head; therefore, the best option is to do it from the printer menu.

Read your manual to learn how to clean the print head of any problems in order to solve the blank page print issue.

Read: Printer keeps printing documents in inverted colors.

4] Check Printing Preferences

Windows 10 users may open their Printer and scanner settings and check if all their Printing Preferences are in order.

Read: Printer not printing in color on Windows.

5] Run Printer troubleshooter

The next best road to take if all the above options fail to work is to run the Printer Troubleshooter in hopes it will solve the problem once and for all.

6] Align the print cartridge

Whenever you’ve replaced your print cartridges, it is very important for you to align them and have them calibrated by the printer. Since this is done via the software and most printers do things differently, we urge you to read your manual.

That’s it!

Why is my printer printing black and white Windows 11?

If the printer is not printing in color and only printing in black and white on your Windows 11 computer, then you must verify if the Print in grayscale option is set. If yes, change it to the Print in color option from the Printer Preferences. You might also need to reset printer settings to factory defaults. Other solutions like re-install the printer driver, running Printer Troubleshooter, and fresh install printer software can also come in handy.

Swift Program To Check If An Array Is Empty

In this article, we will learn how to write a swift program to check if an array is empty. Here we use two methods:

Using isEmpty property

Using conditional statements

Method 1: Using isEmpty Property

To check if an array is empty Swift provides an isEmpty property. This property will return true if the given array is empty or return false if the given array is not empty. For example Arr = [3, 5, 6, 4, 6] so isEmpty property will return false.

Syntax var isEmpty: Bool{get}

Or you can also write it as −

arrayName.isEmpty

Here using the dot operator, we can access the property. Or we can say to use this property we use a dot operator in between the array name and the property name

Algorithm

Step 1 − Create an array of any data type.

Step 2 − Check if the given array is empty or not using isEmpty property and store the result into another variable.

var res1Array = IntArray.isEmpty

Step 3 − Print the output

Example

In the following example, we check whether the given array is empty or not using isEmpty property.

import Foundation import Glibc var IntArray : [Int] = [74, 99, 9, 38, 78, 132] var StringArray : [String] = [] var res1Array = IntArray.isEmpty var res2Array = StringArray.isEmpty print("Is IntArray is empty?", res1Array) print("Is StringArray is empty?", res2Array) Output Is IntArray is empty? false Is StringArray is empty? true

Here, in the above code, we create two different types(that is Int and String) of arrays and then check if the given arrays are empty or not using the isEmpty property and display the final result.

Method 2: Using Conditional Statements

An empty element does not contain any value or element means the length of the array is zero. So using a conditional statements we check whether the length of the array is zero or not. If the length of the array is zero then the array is empty. Otherwise not.

Algorithm

Step 1 − Create an array of any data type.

Step 2 − Check if the given array is empty or not using conditional statements.

if (IntArray.count == 0)

Step 3 − If the condition is true print the array is empty.

Step 4 − If the condition is false print the array is not empty.

Example

In the following example, we check whether the given array is empty or not using isEmpty property.

import Foundation import Glibc var IntArray : [String] = ["Mona", "Pinu", "Moha"] var StringArray : [String] = [] if (IntArray.count == 0){ print("IntArray is empty") } else { print("IntArray is not empty") } if (StringArray.count == 0){ print("StringArray is empty") } else { print("StringArray is not empty") }

In the following example, we check whether the given array is empty or not using a conditional statement.

Output IntArray is not empty StringArray is empty

Here, in the above code, we create two different types(that is Int and String) of arrays and then check if the given arrays are empty or not using if statement. In the if statement, we set the condition IntArray.count == 0 which means the length of the IntArray is equal to zero. If the condition is true, then the array is empty. Otherwise not.

Conclusion

So, this is how we can check if the given array is empty or not either using the isEmpty property or without the isEmpty property. But the most optimized solution is to check if the given array is empty using the isEmpty property.

How To Batch Rename Multiple Files On Mac

On your Mac, giving your files recognizable names makes it easier to find the one you need when you need it. If you have items like screenshots that have default names when you save them or files you’ve received from someone else, you can give them new names.

Luckily, you don’t have to rename files one by one on macOS. In this article, I’ll show you how to batch rename multiple items on Mac using Finder.

How to rename multiple files at once on Mac

But when you have multiple files that you want to rename, this can be time-consuming. Instead, you can use Finder to change the file names.

To begin, choose the files you want to rename. Here’s how to select multiple files on Mac:

Select all files in a folder: Press Cmd (⌘) + A.

Select multiple adjacent files: Choose the first file, hold Shift, and choose the last file in the group.

Select multiple non-adjacent files. Choose the first file, hold Cmd (⌘), and choose each remaining file.

You should see a drop-down menu. Then, use one of the options below to rename your files.

Format text

Using this option, you can format the filename with the name and index, counter, or date with customizable settings.

Select Format in the top drop-down menu.

Choose the following options:

Name Format: Use the name with the index number, counter, or current date and time.

Where: Add the index, counter, or date before or after the name.

Custom Format: Enter the name you want to use.

Start Numbers At: For the index and counter, you can start with any number you like.

Let’s look at an example:

Here, we’ll rename our files using the counter after the name “MyFile” starting at number 1.

For this example, we’ll use the date before the name “MyFile.”

You should see your filenames updated.

Add text to currently named files on Mac

Maybe you don’t want to change the entire filename but add text to it.

Select Add Text in the top drop-down menu.

In the box to the right, enter the text you want to add to the current name.

In the drop-down menu to the far right, choose to add the text before or after the name.

Here’s an example. We are adding the text “IGB” before the name. Again, you can see a preview on the bottom left of how your filenames will appear.

You’ll then see the filenames updated.

Replace the text in name of every file in Finder

One last way you can batch rename files on Mac is by replacing text. This is handy if you want to keep part of the current name but use something else for the rest.

Select Replace Text in the top drop-down menu.

Enter the following options:

Find: Enter the current text you want to replace.

Replace with: Enter the new text you want to use.

Here’s an example of this option where we edit the default names for screenshots captured on Mac. We’ll replace “Screen Shot” with “Mac.”

And just like that, your files are renamed.

How to undo batch renaming of files on Mac

If you have changed your mind and wish to revert to your original files name, just do the following:

Select the files you have renamed.

Alternatively, you may also use Cmd (⌘) + Z to undo the renaming shortly after.

Rename files in bulk!

When it comes to batch renaming files on Mac, you have the flexibility to use almost any name you want. So, you can save time by changing the names manually and doing it in bulk. For more, look at how to show the filename extensions on Mac.
