What to do with Lib-files from Digikey/Ultra Librarian?

Schematic Library Symbols
1

I got a component library for SM04B_SRSS_TB.zip from Digikey. There are two files in it. SM04B-SRSS-TB.kicad_mod file I put in among other mod-files. But what about 2025-02-10_09-58-00.lib file? KiCads help files are old, and either Symbol editor or Footprint editor don’t recognize a lib-file.

Funny or a little scary, I have several folders with Mod-files. I am sure it is very pretty.

Sounds like the old symbol library format. Try registering it with Manage Symbol Libraries as a Legacy KiCad Library type. If successful you can view and then convert to the current format, or copy symbols out of it.

Edit: They would be from v5.1 as that’s when I started with KiCad and I have several such lib files. They start like this:

EESchema-LIBRARY Version 2.4
#encoding utf-8

Thanks, I will try that when I boot up the Win 10 again. I think the lib-file looked like that, or something similar anyway.
