Old Thunderbird files
I seem to have multiple sets of email files. In my profile folder, C:\Users\..\AppData\Roaming\Thunderbird\Profiles\5yx36fcc.default, I have sets of *.sbd folders and mailbox/index files (e.g. Inbox and Inbox.msf). Many of them have old dates (e.g. Inbox had 8/21/2014). But, in the "Mail" folder is a folder "Local Folders", and in it is another set of *.sbd folders and another set of mailbox/index files (e.g. Inbox and Inbox.msf). These files appear to be the active ones. e.g. Inbox has a date of 2/15/2022 (today). So, are the old files in my default profile left over from some previous version? They seem to have not been used since 2014. The old files are using about 8GB of disk space and I would like to delete them if they are not being used. Thanks. JimC

You don't mention the location of the old files. Where are they located specifically? How many active accounts do you have in Thunderbird and where do they store their messages data? You can find that out in Account Settings. The parent folder containing the old files should be named after an incoming mail server. Do you recognize that server name or not? If you do, is it a server for a defunct account that you removed from Thunderbird a long time ago? If it's the server for an active account, maybe you reconfigured your accounts to store messages in the Local Folders account instead of each account having its own separate mailbox, as is the case when using a Global Inbox. It's only you who can tell us how you have your accounts setup in Thunderbird and whether those old files are no longer needed. If they were used by a POP account, it's possible they contain important messages that were deleted from the server after they were downloaded, and they are not in any other folder in Thunderbird.
This has nothing to do with Thunderbird version upgrades. It is a result of changes in account configurations that you may have performed long ago and have since forgotten, or had someone else do and you're really not sure how it went.
Thanks for the reply. To clarify, the old files are in: C:\Users\..\AppData\Roaming\Thunderbird\Profiles\5yx36fcc.default and include files and folders with dates since 2014 (e.g. places.sqlite with date 2/16/2022). The new files are in: C:\Users\..\AppData\Roaming\Thunderbird\Profiles\5yx36fcc.default\Mail\Local Folders In the "Mail" folder, along with "Local Folders", are folders for other email accounts and only one file, "News & Blogs.msf". You mention a "Global Inbox". I think that is what I used to have, but something changed (an account?) and I was not able to get Thunderbird to continue with that configuration. At that time, I did not look into what happened but I think I did not loose any email... Is there a way to have Thunderbird connect to the old Inbox file so I can look at it with Thunderbird? I don't see any option in File/Open to connect to another Inbox file.
Posting a screenshot of the mail folder and the local folders, showing files in each, may be useful.
Are you saying the old files (mailbox, msf and .sbd folders) are in the ROOT of your profile folder AppData\Roaming\Thunderbird\Profiles\5yx36fcc.default and NOT inside the Mail or ImapMail subfolders like those of your other accounts?
Yes, that is correct. Attached is a screen shot of the "Local Folders" folder. The root folder has 225 files and folders so I didn't attach a screen shot from any of it (but I can if needed). JimC
What you posted is a screenshot of the Mail folder, not the Local Folders. If that is where the majority of files are, then yes, posting a screenshot of that would help, possibly sort descending by folder size to get the major ones in screenshot?
Instead of a screenshot, here is a listing (from cygwin) of the files and "folders", sorted by decreasing size. I don't know how to change the font to fixed size to make the sizes more obvious. If this isn't useful, I will do a screenshot. How does this help with the issue about the files and folders in the "...default" folder? JimC

First, to view contents, I suggest a simple freeware program, EDXOR. It is like notepad on steroids. From my experience, sbd files are no longer used, but worth a check. Also, you may wish to confirm the actual folders in use for your account by right-clicking those folders from left pane and clicking Properties.
I don't see how a directory listing of Local Folders is helpful since the old files in question are in the root of your profile folder. No account should be storing files in the root of your profile folder. IMAP accounts store files in the ImapMail folder, while POP accounts store them in the Mail folder, as shown in your previous screenshot. They are, therefore, out of place in the root. Create a new folder in a convenient location such as the desktop and give it an appropriate name, e.g. OLD. Select ALL those old mailbox and msf files, and the *.sbd folders and move them to the OLD folder. This should remove them from the root of the profile folder. It will also confirm if they are still in use by some account or not, because if they are, you will not be able to move them while Thunderbird is running.
You don't need any other program except Thunderbird, to view the contents of the old mailbox files. In Thunderbird, create a new folder under the Local Folders account and give it an appropriate name, e.g. 2014OLD. Create a subfolder under 2014OLD and call it Temp. Next, go to your profile folder\Mail\Local Folders. You will find a "2014OLD.sbd" folder. Copy (or Move) the contents of the OLD folder into the "2014OLD.sbd" folder then restart Thunderbird. You will now be able to access the old messages in Thunderbird, under the Local Folders account > 2014OLD.
Thank you both for your help so far. I am working on doing as suggested by Stans but ran into problem. When moving files from the "old" location (the profile root), I did not exclude the "ImapMail" folder. In the process, I ended with 2 different INBOX files, a short one which moved, and a big one which did not move. I moved everything back except the short file; the short one I renamed and then moved back with the big one. I think I read somewhere that if I were to delete/rename the INBOX.msf file with TB closed and then restart TB, it will re-create the .msf file. If that will work, I will do that to be sure that the file is correct. and then will follow Stans directions to create a new mail folder for the short file, move it with TB closed and then restart TB to create a proper .msf file for it. Does this all make sense? JimC
If the short inbox file is an msf file, don't worry about it. You might as well just delete all the msf files that are in the root of the profile folder. They are of no consequence because they don't contain any data that is worth saving. Thunderbird will recreate them when and where it needs them, so it's safe to omit or remove them from the process I described. They are merely index files for the mailbox files (the ones without extensions, such as the huge INBOX file).
