VirtualBox Shared folders for Windows 7 (host) + Ubuntu 12.04

If "Auto mount" is checked when setting up the shared directory, then nothing in the Linux in guest is moved, and the system automatically creates a mount point with "sf_" prefixed with the share name in "/media", such as the share name you set is "share", then this mount point is "sf_ Share ", the system will be automatically mounted as soon as it starts up. However, because the default permissions for this mount point are "vboxsf" for the user group created by VBox, you will not be able to view it, just modify "/etc/group" and add your username to the "vboxsf" group.
