i have an external hard drive that I have connected to an extra computer on my home network. For school and work, I spend a lot of time at another location. I'd like to access the files on my hard drive but I don't want to bring it with me.

Home computer: Ubuntu 14.04.2 32 bit
Additional computer: Windows 7 64 bit

The files are large movie files also.

Is there software or a networking solution I can use to access my drive?
