Question about AddDir

[sniperdude0]

Hey, i've always wondered this and i'd like a quick answer from someone who knows.
So if I have a script like this:
[lua]
local function AddDir(dir)
dir = string.Replace(dir,"\\\\", "/")
dir = string.Replace(dir, "\\", "/")

local files, dirs = file.Find(dir.."/*", "GAME")

for k, v in pairs(dirs) do
AddDir(dir.."/"..v)
end

for k, v in pairs(files) do
local realpath = dir.."/"..v

if(string.find(realpath, "addons", nil, false) ~= nil) then
local path_array = string.Explode("/", dir.."/"..v)
table.remove(path_array, 1)
table.remove(path_array, 1)

realpath = string.Implode("/", path_array)
end

resource.AddFile(realpath)
end
end
[/lua]

and I have an addon which is called "Cake"
Now inside of "Cake" there is materials and models
Inside of materials there is folder1, folder2, and folder3, and inside of models there is folder1, folder2, and folder3.
Inside of each folder there is a file called cake.mdl
If I do
[lua]
AddDir("addons/Cake/models")
AddDir("addons/Cake/materials")
[/lua]
Will players download the files in the folders folder1, folder2, and folder3, or will it just go into Cake's models folder, find nothing to download, and quit out?
How does this work?
