Hello,
I would like to compile a .ff file (I'm trying to modify an already existing map, adding mechanics from other maps in it), but I have not found a way to compress multiple folders into a .ff file anywhere yet.
Does anyone know how to do this?

Thanks to the ones who will answer.



P.S.
I already tried to do it simply compressing the folders into a .zip/.rar file and change its format, but It doesn't work.

-you could for example just create a new folder in your \root\mods\ folder, name it COMPILE_FF for example.
-then open launcher, go to the mod-builder tab, and put everything you want to compile in the .ff in the mod.csv box.
-tick 'build mod.ff fastfile' and then build mod
-in the \root\mods\ folder you created will be the mod.ff you can just rename it then

This requires UGX tools, right?

just the normal launcher that comes with the tools... nothing else
