You can safely delete most of those older Turbo Lister backup files and get back that disk space - Turbo Lister always creates a new IMB and TLB each time you successfully complete a backup. Although your older backups seem to have no TLBs the way your more recent ones do--not sure if you deleted them or what. If you have more than one user in TL, it creates a different file for each user, and doesn't really tell you which is which (I had to judge by size), but it seems like you only use one user since the sizes are similar each time. I generally only keep the most recent couple of backups, in case of problems, because they do eat up a lot of space. Also I learned the hard way that if you do ever have a corrupted TL database and need to restore it, it will give you the backed up listing data, but the photos will not be there and will have to be added back manually (unless there's a way and I didn't think to ask!).
There are some TL threads on the .com boards, which I'm consulting to try and prepare for the end. I might start another one here because I'm planning to switch to SixBit and I have questions (e.g. can it change listings from Canada to US as needed).
