hello,
I'm downloading right now the entire content of my Gmail account in my thunderbird portable through IMAP.
My gmail is 15GB and 41470 messages. Now I've downloaded almost 3636 message, which means 91% of the entire messages, however the size of my Thunderbird folder is only 2.44% ... how is this possible? I was expecting the same size of my actual Gmail account, is there any sort of compression?
My main goal is that I'd be able to manage my mailbox offline completely, so if I want to search and query for old messages I could do it offline, but this size difference makes me suspicious.
Any input is welcome, thank you!
