Adding models to online servers?

Hey me and a mate just bought a gmod server and I want a http://www.garrysmod.org/downloads/?a=view&id=94368 model on the server. I made it work on singleplayer btw
So when I gotta upload the model for the server I cant upload the folder named haloplayermodels… because… it’s a folder. So the thing is, do I take every single file inside it that is not a folder, and upload it to the server, or do i just make it a zip file and upload it that way?

Please help me im quite desperate

What server host are you using? Most of them will allow you to transfer files via FTP

FTP? What is that?
Well nvm, but lets say this server host can aswell, how would I do this?

FTP = File Transfer Protocol
