The skies in Quake 2 can be files that are tga and pcx, one for each sky position, up, down, left, right, front and back (usual skies).
Or can be just png files for a ceiling used as a artificial sky (sky props).
If you need small sky types when you look at your room or cell window in the game, wal files can help you (windows skies props).
I just tried to keep it simple, but interesting.

Quark 6.6 beta 7 deletes the temporary folder and your mod folder if you click empty temporary directory
Never click this, it will delete the temporay folders inside your mod folder with all your mod folder files, in our case, roarke. It doesen't go in your Recycle Bin.
I thought that will delete env, maps folders, which are temporary in your roarke folder, but deletes all.
I had to copy a roarke folder from another Quake 2 folder, from the same drive and used it.
I used Empty Now because i made and moded sky textures and Quark didn't registered new or old skyies, only the default one.
But when i copied roarke folder from the other Quake 2 folder, the sky problem is no more.
So, Quark has some type of rare stuck temporary files. Just copy your roarke folder and your temporary env, maps made by Quark editor and if you click Empty Now, you have already made a backup.
