Short description of Data Destroyer 11.05: A program for secure file deletion and disk wipe which destroys (or purges, by overwriting) data in files on floppy, ZIP or hard disk so that the data cannot be recovered. A single file can be purged or, in batch mode, multiple files can be purged in one operation. Selected subfolders of a folder, or the free space, or an entire disk can be purged. The user can specify the type of purge. Purge speed can be tested for estimation of purge times.
