Wipe/Delete File Data - We generally think that the files we deleted, is deleted from the disk. But actually they are not; only the reference of the file is removed from the file allocation table (FAT). They still exist on the free space of the disk and can be recovered by any good undelete tool. Wipe/delete File data clears such data from the disk.
