retrieving Cache game files?

in the game I play, Tactical Ops (Unreal mod), all aspects of a map that you download from a server you are connecting to are saved as Cached files (.tmp). Is there a way that anyone knows of to retrieve these cached files and maybe turn them into map files (.unr) or texture files (.utx) ? or are they stuck that way

i want a Map that i have in cache that is not available for d/l otherwise...
