Remembering a directory inside a lua script

loading a decal specifically from the roblox plugin directory

directory : C:\Users[YOUR NAME]\AppData\Local\Roblox\InstalledPlugins

I think this is the only place that roblox allows players to store local data or in this case a decal.

Is it any possible if a plugin/lua script remembers this directory?

Can you tell me what to search for if you know any way?
