Disk Redactor 1.2
Disk Redactor is WIPE utility, that prevent restoration of the old ( deleted ) files at your disks. All free space at your hard disk will be wiped from an old information. This is necessary because the delete function does not clear the space where deleted file is located and just mark the entry in directory ( folder ) that the file is deleted. But actually all information about the file is presented at the disk and can be restored!
