How to use it ?
My friend wants to use it, but wiki isn’t updated.

And by how I meant what functions does it have ?

At times where there is no documentation, it’s best to check the source code.

Then document it on the wiki if you can.

You can also use http://glua.me/bin/ and search for whatever at topright to see if garry has used it somewhere in his code.

Oh, I checked it via GCFScape before making this thread ;D
But ShowFolder() didn’t work properly for me.
