Is there a program to truly delete all deleted files?

I am looking for a tool that wipes (overwrites) unlinked files; preferably something that runs as a kind of disk formatter, overwriting the entire unused portion of the harddrive partition while leaving everything else intact.

If you run Sysinternal's SDelete with the -z argument, it will cleanse free space on the given drive.

sdelete -z c:

This is a good solution if you want to run as a batch file every so often, or if you just prefer a command line tool.

Ccleaner - check the Advanced option, Wipe Free Space.

Ccleaner is freeware, I recommend using the Portable or Slim version (the default installer will install a browser toolbar).

It wont install a toolbar unless you tell it to (AFAIK). –  Svish Dec 5 '09 at 19:27
it will, unless you tell it not to (by clearing the checkbox, which by default is checked.) –  Molly7244 Dec 5 '09 at 19:41
When you install, unless you blindly click next, you will come to a large selection menu. Most of the options I disable. I don't want the Toolbar, or the extra menu options on the Recycle Bin. I do want the Start Menu entries, but not the Desktop Icon. A lot of free utilities do this, and it is an annoyance that likely grabs the unsuspecting or casual user. –  Darren Hall Dec 5 '09 at 21:01
sorry, but it's the 'default' setting and that is a BIG minus (indeed the very fact that this browser tool bar is present in the standard installer qualifies Cleaner as adware in my books), hence my recommendation for the Portable or Slim version, which features ALL the options bar the browser tool bar. –  Molly7244 Dec 5 '09 at 21:30
As long as I have the choice of unchecking it, I don't care. People who just click on next and ok without reading deserves ad-ware anyways. –  Svish Dec 7 '09 at 7:39
