VirtualBox Ubuntu shared folder is empty

VirtualBox Ubuntu shared folder is empty References I have a Ubuntu virtual machine (Virtual Box) hosted on my MBP w/ Mountain Lion. OSX 10.8.6, VirtualBox 4.2.16, Ubuntu 12.4 LTS (32 bit) PROBLEM The shared folder(s) as seen in Ubuntu is/are empty. m TRIED Searching for an answer on interwebs. No joy so far. Share folder in VirtualBox Host=Mac OS, Guest=Debian - No joy. The answer is for manual mounting. Auto mounting explicitly puts/mounts the shared folder in /media directory. Besides I tried it and got \"no such file or directory\' - but then I may not be understanding exactly where I\'m creating this; no terminal guru, I. Next ... Set the shared folder via VirtualBox | Devices | shared folders menu. The dialog box indicates \"full\" access and \"auto-mount\". Then launched the VM. The shared folder is created, but empty. BTW, the folders are created in /media directory per the VB documentation. After launching the VM, in Ubuntu, using VB | Devices menu, creat ed a new shared folder. Restart Ubuntu, folder is created but empty. Next ... Tried the above, creating \"machine folder\" and/or \"transient folder\" - same result as above. Next ... Tried the above referencing folders on both drives on my MBP. Same result. Next ... Tried adding my logged-in user to the vboxsf group in Ubuntu. useradd -g vboxsf someUser Ubuntu responded: useradd: user \'someUser\' already exists
