    Question Virtualbox and shared folders - permissions problem

    This is my first foray into Linux, so please bear with me if this is a dumb question..
    To try out Ubuntu 12.10 Desktop I installed VirtualBox v4.2.4 on my Win7 64-bit Home Premium PC, and installed Ubuntu 12.10 32-bit as a guest OS.
    However, I can't get to share folders between host and guest.

    In Win7, I've right-clicked the folder to share, selected Share with.../Specific people/Everyone/'Read/Write', and named the share "Main".

    In VirtualBox Manager, I've now got the guest OS Shared Folders Settings to show the share under "Machine Folders", with properties:
    Name: Main ;
    Path: c:\users\john\documents\main;
    Auto-mount: Yes;
    Access: Full.

    Rebooted the guest OS, and as stated in the Ubuntu documentation, I now have a folder in File System/Media called sf_Main.

    However, opening this folder, gives me the error message:
    "The folder contents could not be displayed.
    You do not have the permissions necessary to view the contents of "sf_Main". "

    What am I doing wrong? Surely "Access: Full." should give me full permissions? How do I get Linux to recognise the permissions?

    Regards
    John

    Your user in the Ubuntu guest OS must be in the vboxsf group.

    From a terminal, type:
    Code:
    sudo adduser xxxxxxx vboxsf
    where xxxxxx is your user account name. Log out and log back in to Ubuntu.

    Also, make sure the Virtualbox Guest Additions are installed in your Ubuntu guest, and the Virtualbox Extension Pack is installed in your VB installation in Win7.

    wheeze - The Man! Solved the problem instantly. Thanks!

    Took me a few minutes to work out what a terminal window was, and how to open one (just like Windows/run/cmd), but this now works a dream (if a little slow). MUCH better than Windows Virtual PC - couldn't get Ubuntu to install at all in one of those.

    Thanks again!

    How do I mark this thread as solved - not at all obvious....

    a suspicious person could suspect deliberate intent on Microsoft's part...

    In the "thread tools" drop down menu at the top right of the thread.
