Well, when you make a map a bsp file create in: Team Fortress 2\tf\maps
But i made a lot of maps and i have a lot of custom map... is there a way to delet all the maps except valve maps?
yesss, i mean a faster way thant that... cause i really have a lot of maps and sometimes i think some of the maps are official when its not...Yes there is. Though it might take some time. I suggest removing one by one or removing all of them and verifying game cache. Though I highly recommend the first one.
Just filter them by searching using the gamemode prefix (cp, koth, pl).
.... wow... so many comments about this...I think ABS made a tool for this - can anyone remember what it was called?
