You can do this with Box.com accounts too:
File explorer -> right click "Computer" ->Map Network Drive ->
You can have it listed as a network drive, or a folder:
If you want it to show up with a drive letter, enter the following in the Map Network Drive window:
http://www.box.net/dav/
and enter your username / password as prompted.
If you want it to just show up as a network folder, select the "Connect to a Web site that you can use to store your documents and pictures" on the bottom of the screen
Hit Next -> Next -> then specify the Internet or network address as:
http://www.box.net/dav/ ->Next
and enter your username / password as prompted.
It will take 30 seconds or so for the drive to show up.
I use network drives as a way to connect (2) different accounts to my Surface (I have both a Google, and an Outlook(MS) Box.com account). I use one account with the App, and the other with the network drive - you can switch them up all you want. This allows you to browse cloud files in the desktop file explorer, which is useful.
