Or, those files we want to hide because they may contain incriminating evidence. Is there a way to destroy or delete or erase files you don’t want to keep on your Mac, but don’t want others to find? Don’t use the Trash.
Erase Data Like A Pro
Deleting files from your Mac is not as easy as simply moving the files to the Trash can, and then emptying the Trash. Those files are still on your Mac.
The way OS X works when deleting a file is to simply turn off the light that says the file is here. But the file is still on the Mac.
If you choose Secure Empty Trash from the Finder menu, the deleted file is written over a few times making it more difficult to find with a recovery tool.
Or, you can use an app like Data Eraser Pro which costs a few dollars but comes with three distinct file deletion methods to ensure the files you trash are truly trashed.
Here’s how it works.
Data Eraser Pro is drag and drop. Drag a file or folder to erase. Select the method. Click the Secure Erase button.
That’s all there is to it.
1 Phase Normal Erase erases securely, but not so much as 7 Phases or 35 Phases which take longer.
The latter two levels make it virtually impossible for a deleted or erased file to be recovered from a Mac, so use it wisely.
Even Abby Sciuto from N.C.I.S. couldn’t dig up those files from your Mac.
Doesn’t Apple’s built-in Secure Empty Trash do the same thing? Yes, but not as much. Extra peace of mind comes with extra levels of erase and a few bucks.
