Just like paper documents, some digital files are so sensitive and valuable that they need to be encrypted, and when disposed of need to be destroyed with care and deleted securely so there’s no chance of retrieval. How do you do that? Empty the Trash? No. There’s a better way.
FileShredder Shreds Files
Your Mac comes with two options to delete files. Empty the Trash can is one, and easily the most commonly used option. The other option is to securely empty the trash, a better option, but not the best.
First, most Mac users don’t know this but simply emptying the Trash can does not actually delete the so-called deleted files from the Mac’s hard disk drive.
Instead, emptying the Trash simply removes the little digital flag that tells OS X the file is there, and it can be overridden as easily as the file can be recovered.
Secure Empty Trash is another Menubar option which overwrites the files in the Trash can so they’re not easily found, and it’s more difficult to recover and reunite the pieces.
Depending on the value of the files, and what could happen if they fell into the wrong hands, consider another option. FileShredder has even more options to truly delete sensitive files.
Right click. Select Secure Shred. Done.
You don’t even need to select the app to get it to work.
FileShredder shreds files a number of ways. Right click on a file and select from the pop up menu.
However, when FileShredder is open and visible in the Dock, all you need to do is drag and drop files or folders and the shredding begins.
The app’s Dock icon will display the number of files remaining for deletion (and, it can play a sound when done).
The real value of this inexpensive digital shredder is in the Preferences, which control three levels of secure deletion. 1 pass (very fast). 7 passes to be Department of Defense compliant. And the safest, and slowest, the 35 pass Gutmann deletion algorithm.
Considering the nominal price, FileShredder is a very good value made better by the ultra secure file shredding and deletion method. Be careful, though. Don’t use the right-click and select method on aliases in the Finder. The original gets deleted instead.
