Network File Sharing but not allow users copy/save file to local pc

Hi, I am Max

My customer requests for all office file/some autocad pic storage on server,

users connect the server edit/save file, but not allow them save/copy all the file to local pc,

I asked many people, them suggested me try sharepoint,

but them also not sure sharepoint can do it or not,

and I am using window server 2012.

Can anybody give me some solution & ideas?

Thanks, waiting for yours reply
