Iwas sifting through my map files in nexuiz/data/maps and found some new files i have never seen before . example.bak , example.srf example.lin what is this file ? what does it do ? do i need to place in a pk3 somewhere? will it make my computer do tricks?

It will jump if you tell it to.

example.bak is an older version of your map; same goes for example.autosave.map or how that one is called. Delete it.

example.srf is a surface file made by q3map2. Not needed after the light stage. Delete it.

example.lin is a leak line file made by q3map2, used to indicate where a map leak is (GtkRadiant showed you these red lines then). Delete it when you have fixed the leak.

ha ha AI .

ya the .lin was confusing me . i thought it may have been a new file for for an update i ddnt know about . ok thanx divVerent good to see you are still around .
