While posting a link to another part of the forum (Alternatives to NTL) searching the website i came across this utility
SuperShreader (wondered if it would be any use)
When you delete a file from your system (and remove it from your Recycle Bin) the contents can still be retrieved by someone who is knows what they're doing - they can even potentially recover data that's been overwritten! Now this doesn't really matter if you're just deleting some unused Word documents, but if you deal with sensitive data such as encrypted information, then it's VERY important that these files be securely deleted... That's where AnalogX SuperShredder comes in!
SuperShredder gives you the ability to delete files using not only common methods such as Gutmann & NISPOM (DoD), but can be completely customized to give you all the security and/or performance you may need. It can receive files via drag-&-drop onto the application or the icon, selecting files from inside the program, command line, & can even add a shortcut to your 'Send To' menu inside the Windows Explorer so it's simple to delete files in a secure & convenient fashion.
