If you mean you want to access your files from another computer, it can be done but it's not easy to set up. What you would need would be some sort of VPN server installed on your network that you can connect to remotely (this is not one of those "hide your browsing activity" type VPNs) and then set up your OS for file sharing.
If you don't want to go through all this, you would be much better off just using something like Dropbox to sync files.
