How to Resize VirtualBox Disk Images

Thanks! Very Helpful!

thank you! my vista virtual machine was running low on space!!!

thank you very much. it works flawesly

Thank you man! This was super helpful... I didn't want to spend a whole day reinstalling windows 10! I do have one question... lets say my virtual machine has a virus? Is it likely that my "real" computer will get infected if I share files on my virtual machine through the network drive method?
