When you delete a file, the file is not completely deleted. It can still be recovered using File Recovery software (see my older post).If you want to securely delete your files, until no chances of recovery, you can use:
File Shredder - click to download.
It's a program that remove the trace of file completely, so that it can't be recovered even by File Recovery software.
Because it deletes files completely, so please be careful when using it.
