Adding downloaded custom objects?

[N3T3ND]

Hey there guys! I watched a tutorial on how to add created custom objects, such as squares etc..

I wish to add some downloaded objects that i have been given to my server. objects such as the following:

The problem is, I'm very confused on how to go about it, I opened it in 3DS And exported it as a COL And DFF File. The thing is, When i was told to open it using TXD Workshop and Some Collision editor, How would that work? As the object already has textures on it. I tried opening it in my Map just with the COL And DFF. So i added the server.lua and edited the META.XML With the files folder containing the COL AND DFF but the map didn't show up on the "open" tab. Any ideas?

if you can help i'd be really grateful?
