I want to have a directory which is accessible on both Windows 7 installed on Ubuntu host, and the Ubuntu as well.

So I have installed the *Virtualbox additions* on both Windows and Ubuntu.

Then in Ubuntu:

```
sudo mkdir /media/win7share
sudo mount -t vboxsf win7share /media/win7share

```

I get:

```
/sbin/mount.vboxsf: mounting failed with the error: No such device

```

* What do I need to type in Shared folders in Virtualbox Manager settings?
* What do I need to set up on Windows?
