When you delete a message in The Bat!, it is only marked as deleted in the index file (the .TBI file). This has a number of benefits: * Messages can be deleted quickly. * Deleted messages can be restored. * The "Move" function can be safer. It copies then deletes. If any part fails, the message still exists. When you compress, The Bat! reads the index file and removes any messages not in it from the message base (the .TBB files). That is why, after a couple of months of use, compressing can save so much space. Every time you use a "move" filter, a duplicate copy exists in the Inbox until you compress. Your deleted messages also exist until you compress. NB: The message may be marked as deleted in the message base also. To test this theory, delete a message but do not compress. Then, after making the proper backups, delete the index files. Re-open The Bat! and see if the deleted message reappears. If it does, it was only marked as deleted in the index file and not the message base. -- Chris - Nun mi Esperanton lernanta estas. Quoting when replying to this message is good for your karma.
