Thunderbird keeps generating inbox-n folders
I have been running Thunderbird for many years, currently on a Windows 10 PC, and always been pleased with its performance. Using it to monitor 5 email accounts, each on a separate folder. Recently I noticed that on three of the accounts extra folders are appearing named inbox-1, inbox-2, inbox-3... then inbox-5 appeared today. There is also inbox.msf.compact-backup and a couple of nstmp folders. They contain copies of all emails in the main inbox over differing periods but going back to 2016 when it was first loaded.
I assume this is something to do with compacting but why has it started it doing now and how do I get rid of these folders which are, presumably, duplicating all my messages and taking up disk space.

While I do not know why the problem is happening, I do know that the nstmp files can be safely deleted, as thunderbird abandoned them. This happens when compacting fails to complete. That might be due to having large message folders, or small disk space available.
Whenever I try to remove any of those folders, TB locks up, and they only way out is to close the program. Am running version 128.4.2esr (32-bit).
128.4.3 will be available in a few days, which as a fix which may help your issue. After you update, please post whether it helps or not.
