I was going to add that word as answer - yet the "Disco-Files" imho fits better
since Aliens, Mystery, Crime, Investigations may be included in that definition.
(just like the X-Files - just here we have Disco/Freelancer/Sirius)
If we talking on Vanilla Freelancer then instead:
"The Disco-Files" it should be "The Sirius-Files" or "The FL-Files"
