What files do I compress to .uz2?

[thegtz]

I was wondering what files am I post to compress to .uz2?

Do I only compress the kf maps(.roms) or do I compress all custom files?

If I need to compress all files then once I am done compressing them do I upload them all into one folder or follow the folder structure.

Do I need to upload all custome files onto the redirect or only the map file?

Example: KF map the Hive has other files besides the map. Like music, system, staticmeshes and sounds.
