So... I just put in:
ulx addForcedDownload "TiledBlocks" 1
Questionmark
I'm hoping I don't have to get explicit with the files I want to get.
Nope that command didn't work.

I don't really need to send ALL the models I just wanted to send this 5 meg pack. Does that mean I have to explicitly state the name of EVERY file in said pack? Since telling it to send all materials files would be way more than I want or need to push at the user.
Can I at least use wildcards?
Addendum:
I moved it out of addons and put it in a "ForcedDL" directory, pointed ulx at it, and it looks like it found them, but at entry 3925 it crashed and said:
Host_Error: Overflow error writing string table baseline downloadables.
