DeleteOnClick is a very simple to use file secure delete utility for Microsoft Windows 98SE/ME/ 2000/XP/2003 and Vista. Any type of file can be deleted, including NTFS compressed & NTFS encrypted files.DeleteOnClick completely deletes files in one click and the data becomes unrecoverable, and also has the option to wipe free disk space. For this reason you must use the program carefully. Once a file is 'Securely Deleted' no one can undelete it.
