.map Files ?

How i can use .map files on my server ( To use the maps ) Because i usually put a maps as .rar in my server like they are all there. But now i got Downloaded some maps and they are all in one .rar . I'm sorry for the stupid question but i Google alot about this and still got nothing. Dont know how to put this type of files in my server or to use them.

If they're all files of .map format then they're probably MTA: Race maps. You may use THIS converter.
