.vault files query

[Heisenberg]

Hello all, my apologies if this has already been spoke about, i did have a quick check before posting.

So, downloaded a bundle of uploaded maps from gpgnet alpha-labs net and they are all .vault files. Now i presumed they would all be visible in FAF launcher when creating a game but hardly any of them are visible. Oh and also checked in game creating a skirmish as a long shot but yes no luck there either. Is there any conversion process the files have to go through before they are visible/playable?

Thanks in advance
