1. In VirtualBox, select the Ubuntu VM and go to “Settings -> Shared Folders”. Select the local folder that you want to share with the Linux VM.

  2. Boot into the Ubuntu VM. Open the file manager and navigate to the “/media” folder. You should see the shared folder with a “sf_” prefix.

  3. Now when you try to access it, it will give you a “you do not have the permission necessary to view the contents of…” error. The trick to fix this is to add yourself to the “vboxsf” group. Open a terminal and type: Replace “username” with your login username.

  4. Restart the Ubuntu VM. This time, you should be able to access the shared folder.
