disk-usagesoftware-recommendation
I can't really find a great disk analyzing software for Ubuntu.
The default apps in Ubuntu, Baobab (and df -h) do work, but there are no advanced features.
What I am looking for is like glary utilities disk analysis, to search for those file that take too much disk space.
You must not remove the entire folder but you can remove "Old-Packed" log files without harming your system.
For a typical home user, it's safe to remove any log file that is compressed and has a .gz extension (as you can see in the picture).
These compressed log files are old logs that are gzipped to reduce storage space, and as an average user, you don't need them.
