I am using windows 8.1. I installed virtualbox and set up a virtual Ubuntu 13.10 system in it. I want to shared the folder with windows. The folder is the Dropbox folder with rw permission. I can successfully mount the any other folder in my windows except the Dropbox folder. I can only mount it with readonly permission.
I use the command like
sudo mount -t vboxsf sharename /home/username/mountpoint -o rw,exec,uid=1000,gid=1000,dev
Why I can not mount Dropbox with rw?
