TB manages your messages as a database or to be more precisely: stores them in a database. This database is organized per folder. Each folder has a messages.tbb and a messages.tbi file. The real messages are stored in the messages.tbb (The Bat Base) and to shorten the access time to the messages additional info is stored in the messages.tbi (The Bat Index). This additional info can be a flag you've set to the message, the info whether you've replied to it or whether you deleted the message. Deleted? you'll say. Yes. When you delete a message, TB flags the message as deleted in the index file, but leaves it in the actual message base. That's because setting a bit in the index is faster than rewriting the full messages.tbb. In the folder menu you'll see an option 'browse deleted messages' where you can view and undelete your deleted messages. Will TB never delete messages from the messages.tbb? Yes, it can do that, but that's called 'compressing', you'll see an option 'compress' in the folder menu. This means that TB will rewrite both your .tbb and .tbi files and what's deleted is lost 'forever and ever'. You can also compress folders automatically on closing TB. Since version 1.60 you can set this for all folders in the account settings. And in the folder properties you can do this per folder (compress on exit). TB has also a 'purge'option. In the folder properties you can setup a maximum number of messages or a maximum age for the messages in that folder. That's called purging. Purging is the same as deleting, the message is flagged as deleted, until you compress the folder. Purging can be done automatically and manually (from the folder menu) Note that moving a folder (manual or by filter) will create the message in the new folder and mark it as deleted in the source folder. Now you'll see why it is important to compress your folders, especially those that are seeing lots of messages being deleted or moved. (Your inbox is an example of them.) -- Groetjes, Roelof ________________________________________________ Current version is 1.62r | "Using TBUDL" information: http://www.silverstones.com/thebat/TBUDLInfo.html
