Would it be OK to use Bleachbit on the workstation? Of course not in root but just the regular way?

I understand Whonix is persistent and not meant to be amensic. I just want to limit the available files/cache especially deleted files.

Didn’t find anything on it while searching. Thanks.

Since you understand that… Feel free to use it as per:

After using the non root option I got an error pop up. It wouldn’t go away until the workstation was rebooted.

Using the root option bricked the whole thing! It wouldn’t boot afterwards. Fortunately I had snapshots.

Do not use Bleachbit at all!
