I have downloaded a trial version of "TuneUp Utilities 2003" form www.download.com and it has option from where you can undelete your deleted files.
EXCELLENT utilities..must have.
This what the Tuneup utilities says:
File recovery & Destruction: Safety is feasible. TuneUp Shredder for example is able to delete sensitive files in a way that renders them impossible to restore. On the other hand, TuneUp Undelete can be used to restore programs that had already been deleted from the Windows Recycle Bin.
