Tried this with my Mint V8.0 distro.
I selected most options but not the ones that took a long time or the 'experimental' one.
It cleared 713Mb of stuff and I had to log in to the forum again which shows it's doing some stuff it claims to do.
It didn't like Open Office or Vuse though, it listed stuff to delete but threw up error messages when it tried to, 49 items for both in all.
I am not going to question that too deeply
Oh, and yes, I did shut all applications down first.
Thanks for the link Mr Quad.
