Thunderbird recovery

My Mac crashed overnight and the last 4½ months' mail vanished from my Thunderbird inbox. But I have copious Time Machine backups, so can I (without endangering new mail) import the missing mail from some file in there? —Tamfang (talk) 01:51, 29 October 2021 (UTC)

Do you see an mbox file in your profile? The mailbox is stored as a single file, and I think Time Machine is not cognizant of the format used. So you could restore the mailbox, but this would overwrite the newer messages. Do not yet give up all hope; this question on how to merge two separate mailboxes into one Thunderbird inbox got an answer. While described for Windows, I think the ImportExportTools add-on is also available on macOS. Make sure you make a backup of the current mailbox before you engage Time Machine.  --Lambiam 04:33, 29 October 2021 (UTC)

If by "your profile" you mean ~/Library/Thunderbird/Profiles/[redacted].default: no, nothing whose name contains box. —Tamfang (talk) 01:16, 3 November 2021 (UTC)

Addendum. I have two inboxes, "main" and gmail, the latter of which I almost never use; as well as a number of archive folders. Only "main" is damaged. (I have not found the file that contains it.) —Tamfang (talk) 01:21, 3 November 2021 (UTC)

Perhaps there is a file named global-messages-db.sqlite? In that case, perhaps this helps. (Rather than just deleting it, I'd squirrel away a copy first.)  --Lambiam 12:34, 3 November 2021 (UTC)

Thanks, tried it. No visible effect (didn't even lose new mail). I'm guessing the content is elsewhere. —Tamfang (talk) 01:13, 6 November 2021 (UTC)

Create an empty solution in Visual Studio 2015?

Is it somehow possible to create an empty solution in Microsoft Visual Studio 2015? When I try to create a new solution, it always creates a project for me too. I would want the solution to come up completely empty so I can add existing projects to it later on. JIP | Talk 12:42, 29 October 2021 (UTC)
