WipeFS 1.02
rases the free space on hard disks (including Solid State/SSD), USB flash drives etc, to prevent the recovery of information from deleted files. Any data which still resides in that unused space, albeit marked 'free', can be properly and securely deleted by overwriting it.
As you may know, simply deleting a file does not actually delete the content of the file. Instead, the space that file occupied on the disk is simply marked as being 'free', and may exist for a long time until another file is allocated that space (or part of it).
The time it takes to wipe a volume depends on the size of the volume, the speed of your computer (and amount of RAM), and how many passes you specify. Obviously, 8 passes will take approximately eight times longer than 1 pass.
This application needs to create temporary files on the drives whose free space is being wiped. If you choose a drive outside of the drive where your user-account is you will be asked to select a folder in which this app can store temporary files. The root folder is usually the most convenient place. The files created by this app will be cleaned-up after the free space has been successfully wiped or the process is aborted using the "Stop" button.
In the event the temporary files created by the application are not deleted, re-select the drives and then click the "Clean up" button. You will need to supply the folder(s) you choose initially (if applicable) and then you will regain any lost disk space.
