How to correctly clean up long-used Thunderbird profiles

I have a user who had issues with Thunderbird crashing upon load, so I started digging into her profile. While doing that, I found an old "cache" folder which had been last touched in 2018 taking up 1GB of disk space. Turns out that this has been superceded by Cache2 and it was simply wasting disk space, so I trolled through all of our long-used profiles and deleted these files. Whew.

Now, I am trying to find out what other "gunk" has collected over the last 17 years of using Thunderbird! In that same user's profile, I have a bunch of ancient files and folders including a bunch that are 2018 and older. Some of them appear to be archaic logs (i.e. TestPilotErrorLog.Log), but can these just be deleted, or do they need to be replaced by empty files? Others, like 52608742.s, appears to have the same contents as signons3.txt -- but then there is a separate signons.sqlite, too. Are these old text files just itching to be deleted? Similarly, the "Calendar" folder has two files that were last updated in 2006 -- garbage? What about the myriad "prefs-#.js" files (where # is a digit from 1 to 7, not shown)?

Is there any guide on cleaning profiles? Also, can the Cache2 folder be purged? This user is using POP, so ALL data is local, so we don't want to lose anything, but it looks like cleanup is long overdue here.

You could go through the profile folder and investigate whether each file should be kept or not, but I think it's a lot faster and safer to create a new profile, add the accounts and add-ons, and copy address books, calendars, mail etc. from the old profile to the new. Doing the transfer incrementally might indicate the source of crashes, if they still happen in the new profile. Help/More Troubleshooting, about:profiles, to create, delete and launch profiles.

(somewhat dated, but still useful)

The cache can be cleared from Preferences/General/Network & Disk Space.
