The very very old project with a new progressbar as a GUI (if it can be called GUI, lol),
Cleans current logical disk (c:, d:, etc.) free space with ...0101 pattern using only Win API and no direct HDD access. Useful when need to ensure that all deleted data cannot be restored with help of any programmatical way.

press ESC if you're bored to wait the program to complete.

* added multiple instance handling.

here is my version
I need help with it:
When I create a temporary file on the disk to be cleaned, and that disk is compressed (NTFS), I cannot use DeviceIoControl to set the compression state of the file. DeviceIoControl with FSCTL_SET_COMPRESSION just returns TRUE, but the file has still the compressed attribute set.

You might be interested to use the FSCTL_GET_RETRIEVAL_POINTERS parameter for the NtFsControlFile function. This is part of the defrag API in Win2K and up. It returns an array of clusters for the compressed file. I've seen a few other disk sanitisers use this method.
