This program has three functions. Firstly, this program can clean the FREE SPACE on your hard drive to ensure that deleted files cannot be undeleted. Cleaning the free space of a drive does not affect existing files. Secondly, this program can be used to fully erase existing files, so that they cannot be undeleted. And thirdly, this program can create more space on your hard drive by erasing unneeded, temporary files.
For all of FAT12, FAT16, FAT32, and NTFS file systems (Win95, Win98, WinME, WinNT, Win2000, WinXP, and Vista).
Deleting a file normally just removes the file’s directory entry, but the data itself remains on the disk, along with traces of the names of the deleted files. This program completely eliminates the contents of deleted files, as well as the file names, making it impossible to recover them even with specialized equipment. (* details below)
Disk security is achieved by cleaning the disk in nine ways:
1. Cleaning the ordinary free (unused) space on the disk.
2. Cleaning the Windows' swap file.
3. Cleaning the "slack space" associated with each file. (in the registered version only).
4. Cleaning the Recent file list (in the "Documents" menu)
5. Emptying the Windows' Recycle Bin
6. Cleaning the Windows' "Temp" folder
7. Cleaning out temporary Internet files (browser cache and history)
8. Cleaning out the “Cookies” stored on your computer
9. Fully erasing (deleting) existing files or directories that you specify.
10. Optionally erasing traces of names of deleted files in the File Allocation Table.
This program securely cleans your hard drives without your having to first remove all the files from that drive. However, if you need to do a perfect job of securely cleaning your hard disk then see here for instructions.
You should especially consider thoroughly cleaning your hard drive with this program before selling your hard drive to someone else (eg, when you upgrade to a new hard drive or computer system).
* Normally, the operating system does not actually erase the file that you delete, but only removes the reference to the file from the system's file allocation table (by marking the disk space as unused). The file data actually remains on the disk, where anyone can recover it by using any disk maintenance utility capable of direct disk access. The data remains on the disk until that part of the disk is physically over-written by another program, and even then it may be possible to recover some or all of the data by studying the disk with specialized equipment.
Even reformatting a disk is not enough to prevent data from being recovered by the right equipment.
This program uses disk cleaning methods (especially the "Gutmann method") which aim to make it impossible to recover the disk data, even with the most expensive and specialized equipment.
To suit your needs you can select from a range of different disk cleaning methods, including a simple random-character-overwrite, NIS method (National Industrial Security Program Operating Manual of the US Department of Defense), and the very thorough Gutmann method (based on Peter Gutmann’s paper Secure Deletion of Data from Magnetic and Solid-State Memory).
