searching old (ancient) archives

Using Thunderbird 128.7.1esr under Windows 11. I've got a batch of ancient mail that I would like to search. The archive is sitting on an external drive with folders named *. sbd, files named *.msf, and files with no extension. A quick peek at some of those with no extension reveals e-mail messages of the kind I'd like to be able to search.

I seem to recall being able to open such archives from within Thunderbird, but it was decades ago and I'm a little lost. EDIT: I just reinstalled ImportExportTools NG, but I don't see how to proceed.

How can I open or import these? Again, I just want to be able to browse and search.

Many thanks, Jeanne

Chosen solution

- highlight Local Folders - rightclick and select the importexport menu option to import mbox - then, locate and select the file that does NOT have an extension (ignore the msf file) - and you're done.

Thanks so much for your message. I never got an e-mail so I didn't know to come back and check. Hence my delay.

I had hoped to search multiple mailboxes, but you will at least get me started.

Will return.

Thanks again. You definitely gave the solution and importing multiple boxes was among the options, as I'm sure you know.
