I’m betting the root of this problem is on how I originally installed the system but I would like another opinion. Or several.

Running Mint.

After analyzing the disk usage, the folder where Thunderbird is installed is completely full. I have four separate accounts in it but a single one is responsible for taking all the space available, through the imap/sent folder, which makes no sense for me, as I send relatively few messages compared with all the messages I receive.

I already considered just purging the program from my system and completely reinstall it but if I’m going to do that I’m better off doing a fresh system installation.

The system has two disks: a SSD running the system core and a HDD for the home partition. I opted to keep the system core on the SSD to speed up booting (and it worked) and used the HDD for storage because. I prefer HDDs for user files, for longevity reasons. The biggest mistake I made here was not using LVM on the disks.

Any thoughts and criticism on this is welcome.

Thank you in advance.
