I know that on the windows operating system, when you delete a file it's still recoverable. I'd like to avoid simply paving the harddrive with zeros as I would like to keep my OS installation as is, but is there a way to truly delete files that have been previously deleted?
You want to choose the wipe free space option.
No need for additional software.
Drop into a command prompt and use the built-in CIPHER command.
- Quit all programs.
- Click Start, click Run, type cmd, and then press ENTER.
- Type cipher /w:driveletter:\foldername, and then press ENTER. Specify the drive and the folder that identifies the volume that contains the deleted data that you want to overwrite. Data that is not allocated to files or folders will be overwritten. This permanently removes the data. This can take a long time if you are overwriting a large space.
Microsoft offers a free Windows Sysinternals program called SDelete which should do what you're looking for. It seems to perform the same function as
shred does on Linux systems.
Hope that helps.
The excellent PortableApps has two cleaner programs:
Have you tried File Shredder?
