Resource addFile questions.

I’ve recently opened a server and I want my players to automatically download content like Models and sounds.
I’ve looked around and found this piece of code that I’ve modified.

The problem is, where do I put the lua, and what shall I name it? And does it work with Gmod 13?

Source:

Make a Lua file in your lua/autorun/ folder.

And I’m pretty sure it won’t work.

if its a dedicated server put it in “garrysmod/lua/autorun/server/” and name it “forceddownloads.lua”
