Secure Wipe Portable is small utility that runs in the background which allows you to completely remove sensitive data from your hard drive by overwriting it several times with carefully selected patterns. When you delete a file, the operating system does not really remove the file from the disk; it only removes the reference of the file from the file system table. The file remains on the disk until another file is created over it. Secure Wipe removes all the data traces from the hard disk permanently.
