The newer Bleachbit Root has the same drop-down, but during the Wipe Free Space choice says “does not free up space!“.

And that is what we wanted to do, in the first place?

Right?

I see “Make Chaff” but I’m not the gutsy type to just see what might do, or totally undo, on my Mint 20.04 machine!

Which, I have, finally a total replacement for my OLD favorite W7-Pro-64bit,

And the other boot to OS is W10 home, only kept around on my dual boot for reminding me how “HORRID”…. MS stuff really is!

Thank you for your time in this “how TO!”
