Disk CleanUp is a small disk utility designed to clear previously deleted files. Deleting a file will normally just remove the file's directory entry, but the data itself still remains on the disk. CleanUp will completely eliminate the contents of your deleted files. Disk CleanUp provides options to specify an NSA approved disk erasure method and background execution priority. Disk CleanUp works with any FAT16 or FAT32 hard drive, as well as MS Windows NTFS volumes. Facilities are also included to optionally clear web browser and user-specified folders. Disk CleanUp includes DiskWipe, a small console utility that performs the same functions as Disk CleanUp, but can be used with MS DOS or in a batch command file. Disk CleanUp can be configured to optionally place its program icon in the taskbar notification tray.
