How may ways can you delete files from your Mac? The tried and true method is simple. Drag a file or folder of files or an app to the Trash. Select Empty Trash from the Finder menu and the files are gone. Right? Wrong. The files are still there, still available for anyone with the right Mac utility to find. Alright, how about using Secure Empty Trash instead? That’s better because it writes over the files multiple times, in effect a digital shredding.
Here are a couple of additional options, both called File Shredder.
The first, File Shredder, has three options. A single pass erase, a seven pass erase, and an ultra secure 35 pass erase (takes 35 times as long, too).
File Shredder #1 is simple enough to use, too. Select the type of shredding you want from Preferences. Then, select a file in the Finder, right-click to open the Services menu, and select Secure Shredding.
File Shredder isn’t bad for a couple of bucks.
A few dollars more gets you another file shredder called FileShredder (no space between the two words). This one works much the same way and has similar options, starting at 1-pass shredding, then 7-pass shredding, and finally 35-pass shredding.
Select the file or folder of files. Select Shred or Secure Shred from the right-click menu and the files are toasted.
File recovery is something of an art form so it wouldn’t surprise me that government spooks and hackers have ways to recover shredded files and piece together incriminating evidence, but either version of File Shredder makes their job a bit more difficult.
