Tips:
1. If you have Windows 7, Windows Vista or Windows 2008, we recommend that you run Delete Files Permanently as an administrator so you have permissions to delete all necessary files, wipe free space and wipe the Recycle Bin.
If you use Windows XP/2003/2000/ME/98, make sure you have administrative privileges.

2. If you use anti-virus scanner that checks files saved to the disk, it could slow permanent deleting files, wiping free space and Recycle Bin as the anti-virus scanner checks files after each overwriting/verification pass.
