Moving to Local Folders and doubled filesizes

Thunderbird Import and export email

Hi,

I wanted Thunderbird to stop downloading messages from an old gmail account, but wanted to keep a kind of archive, so what I did was dragged all the account folders (Inbox, Sent, Trash) to Local Folders so that I can continue to reference downloaded emails (the account was using POP, not IMAP).

I'm on Windows 11. Inbox file is basically the same size as it used to be (just now in Local Folders) but Sent, Trash, other subfolders have all almost exactly doubled in filesize compared to what they were before I dragged (moved) the folders to Local Folders. I don't think there are doubles of messages when I look in Local Folders or anything.

Any ideas why the double filesizes? All the .msf filesizes are like, 15% smaller for some reason.

Thanks.

have you tried compacting the folders? I would

Yup, compacting won't do anything, that's what I tried at first.

To be clear, compacting *did* remove the large files from the old folders after I moved them. But the new moved folders in Local Folders are still double the filesize. Something about it being exactly double is pretty weird and suggests something funny is going on.
