I have been using Thunderbird for years and have huge number of emails saved. I was reorganizing to try to get things more manageable, and was putting all my personal emails in one folder (with numerous subfolders for different people). I was moving one folder into the primary folder when I received a message that the disk was too full (which was wrong as I have over 300 GB free space).

When I got rid of the message, the primary folder was still there, but the only folder under it was the one I was moving in. All of the others were gone. All other folders (many) separate from this particular primary folder were still intact. This is a POP account.

I exited Thunderbird and re-opened it...No help. Rebooted computer...No help.

If anyone can help, I would GREATLY APPRECIATE it. Thanks.

usually such problems are cause by anti virus programs locking files to scan them simulating no disk space.

open the troubleshooting information on the help menu. click the show profile button. Close Thunderbird. in Windows file explorer delete the file xulstore.json Restart Thunderbird

That should force Thunderbird to scan the disk for folders that might exist and not be shown, by deleting it's "cache" but you might be out of luck with your mails.
