How many impab files should I have in my Thunderbird profile folder? I do have 8 different e-mails managed by Thunderbird (in case that matters). Win 10 Pro PC, Thunderbird Version 128.4.2esr. I have impab.mab (dated 2017), impab.mab.msf (dated 2012), then I have impab-1.sqlite, impab-1.sqlite.shm, impab-1.sqlite.wal -- then I have -2, -3, -4, -5. and -6 of the same three files that have the -1. Should I/can I delete any of these? Should any be kept and renamed? The ones with -1 through -16 are all dated either today (11/25/2024) or 11/19/2024. Just did not know if there were a bunch of duplicate files being created, or if possibly all of these files are needed because of my multiple accounts. All my accounts use the same address book. Also, been using Thunderbird since I started on the internet back in the 1990s - it's in general a fantastic program.
