The problem here is the idea that Undelete is for emergency recovery of files, but Undelete is not intended to recover files deleted before installing Undelete. It usually can recover the files, but often, especially on C:, the files have already been rendered unrecoverable by Undelete or Emergency Undelete because the files have been partially overwritten, or their index or directory data is gone. In such a case, a utility specifically designed for such recovery is needed.

The key to using Undelete is to have the software on the system before the file is deleted. Deleted files are saved in the Recovery Bin and protected from damage. This guarantees that you will be able to recover the file in question from the Recovery Bin; if Undelete had been on your computer before the lost files were deleted, you could have recovered them a few seconds. You will definitely be in a better position having Undelete installed, as you will almost certainly find yourself in the same or similar situation in the future. With Undelete, you will be prepared.
