In MS Windows I am used to a daily routine of cleaning-out, among other things, '.tmp' files.
In Ultimate Edition v/ 3.0 I recently got into "Ubuntu Tweak" (v/ 0.5.14). Upon getting into the "Package Cleaner" link, I notice the following buttons: "Clean Packages", "Clean Cache", "Clean Config", "Clean Kernels" & "Purge PPAs".
Is there anything in there (those buttons) that I need to routinely clean-out? If so, what?
If not there, is there anywhere else that I should be scrutinizing for cleaning-out junk files? If so, what files should I routinely (and safely) clean-out?
Thank you in advance!
