It is common knowledge to the “geek world” that when you delete a file, it is not actually removed as such from your hard drive, simply the link to the file is removed, and at a certain stage, it is over written with your new data.
On PC, there are numerous programs to ‘permanently delete files’. However, all this does is creates a random document and replaces your existing data with dummy text. There are programs for Mac also, however there is one built right on into Mac OS X.
Remember that after you permanently delete files, there is no chance of recovering them, even with programs that allow you to recover items you have deleted.
In Mac OS X, you can overwrite these files 7 times from the trash. Move the items you wish to permanently delete to the trash, open the trash, then select Finder - > Secure Empty Trash.

You will then be prompted with a warning, read this carefully, you can’t go back!

Then you will have a normal emptying trash screen. Be patient, securely emptying the trash can take a long time.

Please comment and digg.

No Way! I’ve using macs now for over 10 years, and never knew about this. I’ve just looked it up now. I think I have noticed it before, but never looked into what it was. Thanks for the tip.
