From the developer:
This program allows you to specify a directory (and optionally all subdirectories) in which all files should be deleted. When each file is deleted the contents of the file are filled with random data prior to deleting the file. Use this program with care, once you've deleted data using this program, you will have little chance of recovering the data.
