How to delete files permanently
There are two ways to delete files permanently:
- using the 'Delete Permanently' option integrated in the Windows Shell

 Tips:
1. If you have Windows 7, Windows Vista or Windows 2008, we recommend that you run Delete Files Permanently Portable as an administrator so you have permissions to delete all necessary files, wipe free space and wipe the Recycle Bin.
If you have Windows XP/2003/2000/ME/98, make sure you have administrative privileges.
2. If you use an anti-virus scanner that checks files saved to the disk, it could slow permanent deleting files, wiping free space and wiping the Recycle Bin as the anti-virus scanner checks files after each overwriting/verification pass.

Run Delete Files Permanently Portable
Click the 'Tools' button  in the toolbar.
Select 'Delete Permanently'.
Select a wiping scheme from the drop-down list.
|
 Note: The more passes a wiping scheme has, the more time the process takes. Unless special security is desired, the single-pass, double-pass or triple-pass wiping methods are sufficient to prevent data recovering.
