huge Inbox

more options

I have wondered in the past, why the Inbox file (without extension) is so big. Today I moved all subfolders and remaining message from the Inbox. So there is literally NOTHING in the Inbox, but the Inbox file is still nearly 3 GB. How is this possible?!? Are there invisible files, settings, etc. saved in it? Is there a way to reduce the file size?

Also the Drafts folder/file is 1 GB but there is nothing in it. I just emptied the Junk folder and it still shows up with nearly 1 GB. This is very strange.

Please advise! Thanks!

Messages are just hidden from view when they are deleted, and are only permanently removed when the folder is compacted (Compact from the right-click menu).

Thank you for the helpful answer @sfhowes.

Unfortunately, the link leads to a page that has last been updated in 2017. I know how to compact individual folders, but I can't find the general option for automatic compacting in my version (102.9.1 (64-bit)) on my Mac.

It should be a recent document: Compacting folders.

Thank you - must have been some kind of temporary blindness - I finally found it after scrolling down for the umpteenth time
