I have been using Thunderbird for a few months and after a while it started doing really weird things. I found out that it was 98% full according to the progress bar at the bottom. I downloaded attachment extractor add-on and it worked ok and freed up space and NO percentage or progress bar was shown for a while until of course it filled up again after just a week or so. All I want to do is stop Thunderbird from saving a copy of the outgoing attachments in the "sent" mail folder. It's totally unnecessary as I keep the original files in a folder and don't need another copy. I specially don't need copies filling up space and causing Thunderbird to make a big mess. Is there a way to change settings to do this and if not PLEASE tell me why there is not. It makes much more sense to me to have the option of NOT saving exact copis of every outgoing attachment. It also saves the signature file, a separate copy for each outgoing email. This is silly and also absolutely unnecessary.
