On Ubuntu on Virtualbox Using Samba Server Instead of Virtualbox File Sharing
By w̶i̶e̶l̶d̶l̶i̶n̶u̶x̶.̶c̶o̶m̶ author Morgan Jassen
Instead of trying to install File Sharing in Virtualbox, I installed samba server on the Ubuntu Server 14.04.3 virtual machine guest (with "Host Only Networking" on).
It worked. I was then able to transfer files via Windows 7 (that was running Virtualbox) and the Ubuntu Server on the virtual machine guest.
I used this as a guide: "https://help.ubuntu.com...SambaServerGuide"
