RPI 2 ubuntu mate home file server?

Bit of a translation error - but I think I know what you mean.

Caja is the name for Ubuntu MATE's file manager, installing caja-share enables the functionality to the right click menu, as illustrated in this post. There is a stand-alone Samba utility as well to manage file shares, samba and gadmin-samba (a frontend), should you choose to use Ubuntu MATE.

@Wimpy's suggested distro is better suited for your needs. :slight_smile:
