I installed Ubuntu guest on a Windows 7 machine using VirtualBox. How can share folders between Ubuntu guest and Windows host? Thanks.


If you get Permission denied when accessing the mounted shared folder, run the following command:

sudo adduser <yourUsername> vboxsf

Substitute <yourUsername> by your actual username (e.g. john or whichever is yours).

Then restart and you should have full access.

    Logging out and in sufficed in my case, a full reboot was not needed. – Melebius Oct 14 '17 at 9:13
  • Doesn't work on Windows 7 host and Lubuntu 18 guest. – Gustavo Aug 14 at 13:05

run this on your terminal and everything is going to be fine:

sudo mkdir /media/(folder-name-on-linux)
sudo mount -t vboxsf (folder-name-set-on-virtualBox) /media/(folder-name-on-linux)

(folder-name-on-linux) will be available easily on your File Manager

PS: That way you won't need to restart your VM ;-)

  • This solved it for me. For any future travelers: you may need to run that second command everytime you restart the guest. Does this mean something else is broken? Probably... But it works for me when nothing else did. – isick Oct 23 '18 at 1:08
  • Works for a round. After reboot the sharing is gone. – Gustavo Aug 14 at 13:06

Close out your guest VM, and then open up the Settings dialog for that VM. Down near the bottom of the left hand navigation area in that dialog should be an option for shared folders.

You can select which folder(s) on the host machine you want shared with that particular guest VM, whether you want them mounted read-only by the guest, and whether to make them available on boot of the VM. Once done, restart / restore the guest VM and you should be able to navigate to the new filesystem or folder.

I usually make a new folder inside the 'VirtualBox VMs' folder in my user directory, titled 'Shared' and then share that folder with any guest VMs that need it. I mount it read-only so that no one machine can b0rk it for the others, and then I can place any necessary files in there that are desired.

  • Thanks for the answer. After restarting the guest VM, I opened the "Home" folder on Ubuntu(guest), but I still could not find the "shared" folder created and mounted. – user288609 Dec 18 '12 at 22:04

    It is not normal to mount file systems under a user's /home; look for it in the file system. If it doesn't jump out at you in Nautilus (the file explorer app), it may be under /media/ or /mnt/. I'm not sitting in front of a box with Virtualbox on it at the moment so I can't be more specific than that for now. You may need to have Guest Additions installed on the guest VM - other distros like Debian and SuSE auto-install some version of them; Ubuntu does not. – memilanuk Dec 18 '12 at 22:39

you should make the option of "insert guest addition CD image" active, from the devices menu, in order to enable shared folder. the shared folder should appear in the /media.


I had the same problem but after reading another question on this site, I discovered that running

gksudo nautilus

made it work fine.
