.rom files go in the maps folder, just like all the other .rom files.
If your not sure where you need to upload a file, go through your folders ont the server and look for similar files. i.e. .rom, .ukx, .uax, utx, or whatever.
I think that ror folder is just the top level folder of the directory on your server. FTP the like files to the location of other like files.
Did your company create, or is there, a redirect folder? uz2 files go there.
Have you tried to upload anything yet? If not, do it, load the map, and try to join. When you download the .rom really fast you did it correct. When some skin or texture or .rom file goes 1%..........................................2%......................................3%.........you did it wrong.
Oh, and dont be afraid to screw it up. Its going to happen. You may even have the ability, by clicking a button on your server control panel, to reload everything stock. Play with it, stay organized so you can undo anything you did. Your going to screw it up eventually. Dont sweat it.
