GUI program to shred or wipe files with options to make sure they are unrecoverable?

I have a quick question about file shredding. Is there any application with graphical interface capable of shredding files and folders?

I know bleachbit has that feature but there are no options or configurations and I really can't know if the files are unrecoverable or not.

The easiest option I could find with your requirements is nautilus-wipe.

• Go to the Software Center, search for nautilus-wipe, and install it.

• After installing, you'll need to completely close Nautilus. The easiest way to do this is to log out and log back in.
• Open Nautilus, navigate to what you want to wipe, right-click on any file/folder to see the options Wipe and Wipe Available Diskpace
• If you click on wipe, you will see the following:

• You can configure the options (type of wipe, number of passes, etc.) by clicking on the Options triangle:

• Clicking Wipe Available Diskspace on any item or within empty space in Nautilus will offer to wipe free space on the that partition:

• Close Nautilus when done.

You can also use bleachbit . It can be installed in the Software Center.

I realize OP asked for a GUI option, nevertheless, for those needing a scriptable comand-line option, You may use 'shred' from GNU coreutils.

     man shred
