Thunderbird keeps asking me to compact folders with high estimate of savings
Thunderbird keeps asking me to compact folders, c.f. the attached screenshot. Meanwhile, I also checked the profile files under AppData\Roaming\Thunderbird\Profiles, the whole folder of the profile files has only 24.2 MB (25,477,204 bytes).

Repeated requests to compact often indicate a corrupted folder. Try rebuilding the folder by copying the existing mail to another folder, then deleting the folder's mbox file and msf file, e.g. Inbox and Inbox.msf, from the profile folder. TB will automatically create new files on restart.

Check settings at Tools>Preferences>General under Disk Space. Changing settings there may address the issue.

You see the folder of this profile only has 24MB. Why would it ask me to compact folder and said it would save 102MB of space?
