If the person who takes your device is a computer geek, chances are he or she can recover your private data — even if you have deleted them by emptying Mac Trash.
That’s why you’ll want to make sure none of your personal information is retrievable. Sure, the most secure method is to destroy the device, but its residual value would become zero.
The best solution? Using a Mac file shredder app!
Why Do You Need Mac File Shredder?
Let’s start with the basics. When you drag a file or folder to Mac Trash and then delete it there, or you delete it from an external hard disk drive, the file isn’t removed permanently at least for quite some time.
What happens is your file or folder is simply erased from the file directory of your Mac or external HDD. By using a third-party Mac data recovery software, you can recover it provided that it is not overwritten — i.e. you haven’t added new files to your Mac or the external drive.
To make that file unrecoverable, you can either keep saving new large items to that drive manually or use a third-party app to do so automatically. The former option can be quite time-consuming and it’s often not secure because you can’t tell whether the space contained in that file or folder is occupied or not, particularly if your hard drive has a large volume. That’s why a Mac shredder utility comes into play.
