Wouldn't you love to rid of some or all files on your Mac forever. Be it for storage space or reselling it. Perhaps your Mac is too old to take the next operating system version, or you’ve stored a lot of data on it, and you’re worried that it could be hijacked if stolen.
So if you want to permanently erase deleted files, you should find a tool to wipe the free disk space and overwrite the free disk space with zero or random bites. Permanently Erase Deleted Files on Mac with Super Eraser for Mac. DoYourData Super Eraser for Mac is a comprehensive data erasure tool. It offers an option to erase free disk space to. If you absolutely must remove those files (say, if you want to reset an app to its default settings), you can use a handy app called AppCleaner to fully uninstall an app, along with all its extra files. Just launch AppCleaner, search for an application in its main window, and click on it, then click the “Remove” button in the popup window that appears.
The last thing you want is to see that your data was leaked by some hacker, leaving you vulnerable and without a clue of what to do next.
The good news is you can permanently delete files from your Mac using several methods that we’ll show you in this guide.
Can My Files Be Retrieved Once I Delete Them
The short answer is yes.
Data recovery technology has made it possible to recover files and restore them, which means someone else can retrieve any files you delete from a hard drive.
Most new Macs come with the solid state drives (flash storage) or Fusion Drives for some iMacs, instead of the old spinning hard disk drives. That is a critical factor when it comes to securely delete files on your Mac because you won’t have to do so if it comes with an SSD.
If you have an older Mac, it probably has a regular HDD, but the newer models with the SSDs allow you to use the standard method of moving files and emptying the trash to erase files, compared to securely erasing the files.
Unlike HDDs, where secure file deletion works, it doesn’t with the SSDs because overwriting a file only creates a new one in a new location but doesn’t overwrite the old file’s contents.
Thankfully though, there are different methods you can use to permanently delete files on your Mac, whether it has the old HDDs or the SSDs.
Note: You can check the storage on your Mac by clicking the Apple logo at the upper left side of the screen, and then going to About This Mac>Storage. Under the disk icon, you'll see whether your Mac has a spinning HDD or an SSD. Move Files to Trash
This is a tried and true method of deleting files on your Mac by dragging it to the trash. You can also use the Move to Trash feature by right-clicking the file and selecting the option. From here, you can go ahead and empty the trash.
Delete Immediately is a feature introduced by Apple with OS X (macOS) 10.11 El Capitan that bypasses the trash when you delete a file. It’s much faster than Move to Trash as you simply highlight your files and then use the Option-Command-Delete shortcut.
Alternatively, you can go to Finder’s File menu and hold down Option key to change the Move to Trash option to Delete Immediately. You’ll be asked to confirm the deletion, just as you would when using Move to Trash option.
If you want to skip the empty trash confirmation, go to your keyboard and press the shortcut Command-Option-Shift-Delete. That will bypass the dialog window to confirm the deletion and empty the trash instantly.
If that is too difficult for you to remember or cumbersome, change Finder preferences setting to kill the confirmation. Go to Menu>Preferences and uncheck the Show warning before emptying the Trash box under Advanced tab.
Secure Empty Trash
This is another simple solution to deleting your files permanently from your Mac. It ensures that the items are deleted forever by writing random data over them multiple times.
The feature came with Mac OS X 10.3 Panther. It overwrites data seven times to increase security.

To use this feature, click Finder menu and select Secure Empty Trash just below Empty Trash.
Use a Third-Party App
If deleting your files by emptying the trash doesn’t help, you can get a third party application to force the trash to empty. There are many such apps available like Permanent Eraser or Clean My Mac, which can help you empty your trash completely and permanently.
Use Mac Terminal
Mac’s Terminal is a command line tool that allows you to complete tedious tasks such as file deletion easily in just a few seconds. The program uses Unix commands to perform several functions easily and quickly without the operating system interfering with its processes. It’s efficient and powerful as it helps you remove files with ease, permanently.
However, if you haven't used the command line, Terminal can be dangerous too. Before getting into it, familiarize yourself with some basic Terminal commands, because any wrong command you enter can cause damage to your system, and you could easily delete files faster than you’d have time to stop the process.
The precision of every character, including capitalization and spaces, is important when using terminal commands.

To get started, take the steps below:
Step 1: Open Finder and click Applications>Utilities>Terminal.
Step 2: In the new window, a command prompt with the $ (dollar sign) will appear. The command line you’ll see is ComputerName:CurrentDirectory ~Username$ and the word Bash at the top, which is the Terminal language in a Mac.
Step 3: Type your command and press the Return key after each command to execute it, or copy and paste the command into the terminal window. Type rm and space, and then drag and drop the file(s) you want to get rid of permanently into the Terminal window. Press Enter to remove it forever.
Note: You can also enter the file’s path into Terminal if you want to remove the file even faster without using drag and drop.Easily Delete Files for Good
Before you delete the files, make sure you have a backup of your data in case something goes awry. Of course, we would recommend you to get familiar with Terminal for it can be extremely powerful in erasing files while the interface may suffer a glitch or would be slow.

One of the most basic computer functions — deleting files and folders — is also one of the most essential. If you never get rid of anything, soon enough all those extra gigabytes will take a toll on your Mac’s processing power, RAM, and hard drive, not to mention your digital life will resemble a dreadful episode of Hoarders.
So deleting files is good and healthy. But how do you do that? Most people right-click on what they need gone and choose Move to Trash from the menu or use the File option in the menu bar. Others employ the ⌘ + Delete shortcut, which works across the system (even within dialog windows). Experts, however, often find themselves defaulting to the command line delete directory feature. Let’s see how and why you should learn it too.
Why delete file command line feature is important
Since macOS is a Unix-based system, nearly all system tasks you do every day with the help of its graphic interface can also be performed via the command line tool called Terminal.
With regards to delete file or delete folder command line functionality, Terminal lets you:
- Effortlessly erase one or multiple files, folders, and apps, bypassing any error messages you can get when you go the traditional route.
- Remove files from Trash, including ones you can’t delete by simply emptying the trash.
- Get rid of files that are invisible to you within Finder (usually system or root files, for example, .htaccess).
- Delete files and folders in cases when Finder is unresponsive.
Note: The Mac command line delete file feature is final and irreversible. While it lets you avoid any error messages, it also removes the files completely, without any possibility of retrieving them later on.

Secure Erase Mac
Removing files from your Mac forever using Terminal is deceptively simple: just use the rm command followed by the name of the file. Here’s how it works in practice:
- Launch Terminal from your Utilities folder in Applications.
- Check which directory you’re in by typing ls -la
- Then navigate down a directory with cd [directoryname] or up a directory with cd ../
- When you’re in the same directory as the file you want to delete, type rm [filename.extension]
- If you want to delete multiple files at once, list them all, but make sure there’s a space between each one.
- Press Enter to execute the command.
Now all the files you specified after rm are gone for good. Navigate directories in your Mac and repeat the process as many times as you want.
Surprised there was no confirmation before your files were deleted? Luckily there’s a way to add one as a safeguard for not deleting the wrong file by accident. Just use -i after the rm but before the first filename, like this: rm -i [filename.extension]. Terminal will then ask you whether you’re sure you want to delete the file. Reply y or yes followed by Enter and the file will be gone. This also works for multiple files, but you’ll have to confirm the removal of each one separately.

How to make command line delete directory
Surprisingly, you can’t delete a folder using the rm command because it has its own: rmdir.
Otherwise, rmdir works exactly the same as rm:
- Navigate to the appropriate directory using Terminal.
- Type rmdir [directoryname]
- Hit Enter.
Sadly, you can’t use the -i hack when you’re deleting folders, so be extra careful!
Another thing to keep in mind is that rmdir only deletes the directory, but can’t delete any files or folders located within that directory.
To delete a folder with everything in it, you need to use rm -r followed by the folder’s name. Using -i to create a warning here is possible and done like this: rm -ir [foldername].
When it’s too difficult to find a folder or file via Terminal, but you can detect them in Finder, simply drag and drop the file onto the Terminal window to generate its path.
Find and delete heavy folders in seconds
Terminal commands are indispensable when you encounter stubborn files that just won’t go away, giving you all kinds of errors. But when you want to offload some space-hogging files and folders (including invisible ones) to release some much-needed Mac productivity and speed, you need to use an efficient app that can help you avoid manually navigating directories up and down.
CleanMyMac X is exactly what you need. It’s one of the best Mac optimization utilities in the world and contains a wealth of useful features, from streamlining your system files to scanning your Mac for viruses.

- Navigate to Space Lens in the sidebar.
- Click Scan.
- The app will graphically show you which files or folders take up the most space in each directory. Navigate through them all and check the ones ready for deletion. When done, just hit Remove.
