This tool offers you secure and permanent file deletion
If you are wondering how all those undelete programs out there can magically bring back deleted files. Well, that's not really a magic at all. When you empty recycle bin in order to permanently remove deleted files from your hard disk, Windows does not actually remove them. Instead, for performance reason, Windows simply mark the location of deleted files on hard disk as unoccupied and reserve them for future writing.
Hence, until Windows decides to write a new data at the same location of deleted files, those files theoretically still exists in hard disk. If you want to recover deleted file from harddisk, simply scan through all unoccupied areas in your harddisk and try to find data that match the profile of file that you're looking for. When you find them, write those data into a new file. This is how an undelete program works.
If you want to permanently delete files all you have to do is force Windows to write a new data at the same location of the file that you want to delete. This is how a secure delete program works. Currently, there are several algorithms that can be used for securely overwrite deleted files.
TweakNow SecureDelete is a most useful tool designed to help you permanentlly delete files and folders from your hard drive.
This application supports two of the most common used algorithms: Gutmann and DOD 5220.22M. As addition the program also support overwriting deleted files using series of random character multiple times. This method might be less secure, but faster than the other two methods and still safer than standard Windows delete method.
