Bugzilla

I think we have an issue in that most users have no idea what a "disk space" threshold is or why they would want to recover disk space.  I think we should also specify what folder we are going to remove the previously deleted messages from.

Most support topics that talk about compacting  in other than data loss terms sound befuddled as to why we would be obsessing about 1 or 2 mb of space they have 600gb or in many cases most of 2Tb free,  so the conversation starts with what is wrong with you people obsessing about such a piddly amount of recovered disk space.  As the dialog is already wordy. I suggest we look at is in a more explanatory manner.

"Thunderbird does not remove messages from a folder what you delete them.  It simply marks them as deleted.  Complete the deletion process now and remove (number of deleted messages in the folder) deleted messages from the  (insert folder name here)"  that optionally could add "Do this in future without notifying me"

Personally I would like to offer round robin and offer to recover the messages that are about to be removed.  Or at least offer to "show me some of what will be removed" and show the 10 oldest from and subjects.  While the terminology we us is frightening there is no escaping the fact we are actually permanently and irrevocably removing user data,  hidden or not. 

There is nothing like having 2 or 3 year old messages suddenly reappear that you thought were deleted to demonstrate the issue and it is not disk space and never has been.

I would just like to migrate to maildir so we can forget this stuff really.  Until then I think explain and suppress the notice where possible.
