It completely removes a file from your disk without leaving any track. It is very fast. It overwrites any deleted file with blanks or random data N times - where N is given by the user. Also, it changes the filename.

1.5 Development Test 1 (2011-04-14): Initial release
I was looking into releasing this, but it is a .NET app. It uses the batman logo as its icon (trademark infringement) so we'll need to recompile it with a different icon before release. I've prepared a replacement icon here. It's from the Linspire Clear icon set under the GPL.
Sometimes, the impossible can become possible, if you're awesome!
It even says right on their SF page. D'oh.
I'm going to mark this app as discontinued. It's .NET (I've no idea when will be officially supported by the platform), uses a copyrighted logo (I don't want to deal with recompiling), and we already have an app that does the same thing anyway.
