OO UnErase allows users to rescue important files that have been deleted from the hard disk as a result of a virus, malfunctioning software, or simply by accident. OO UnErase reinstates data security when it appears to be too late. It is easy to use and works on systems operating with Windows NT, Windows 2000, or Windows XP. Any time the user accidentally deletes important files that haven't been backed up, OO UnErase can be used to search the hard disks quickly and recover the data.
