Windows (desktop not server, for that you NEED desktop experience) comes pre-ready to mount remote WebDav shares. Seeing how it lacks SSH/NFS/FTP and everything else it seems.... windows..... anyway I was saying. This is the one protocol it comes with and if you say, go to the library and hop on a computer, its cool to mount your entire server!
Anyway the CLI Syntax:
If you don't pass UNAME/PWD it just prompts, thats more for a saved CMD file that you use often on a trusted system.
Note: For other OS's and the source post read here. I noticed there article doesn't use /owncloud/webdav but just /webdav. Perhaps It is because I use proxyPass but I am thinking the article is outdated.
