Clean Disk Security 7.61
Description by Software Developer:"This program gives you secure file deletion, making sure that deleted files cannot be undeleted again. Deleting a file normally just removes the file's directory entry, but the data itself remains on the disk. This program completely eliminates the contents of deleted files. The highly acclaimed Gutmann disk cleaning method is now available as an option. This program can also clean the Window's swap file, and can optionally clean unneeded temporary files from your hard disk, such as your Internet browser cache, files in your system's Recycle Bin, and can clear the "recent files" list. Comes with a direct disk viewer for discovering exactly what is on your hard disk."
Clean Disk Security adds an "Erase fully" option to the Windows Explorer context menu. To delete a file or folder, simply right-click on it and select "Erase fully" from the pop-up menu. The program then gives you the option to select the wiping method. Available options: simple (1-6 passes), NIS (7 passes), Gutmann (35 passes).
Also, Clean Disk Security can be used to clean standard free space on your hard disk, as well as clean file slack space; it deletes Recent files list, empties Windows Temp folder and the Recycle Bin, erases Temporary Internet Files, and cleans Windows swap file.
Limitations of the unregistered version: Does not clean file slack space when cleaning the free disk space.
