How to Fix Windows 7 Sharing in VirtualBox

In my last tutorial on VirtualBox (virtualization software free from Sun Microsystems) that offered a solution to fix the USB support, a problem which I think is fixed now, but ... Recently I found another problem: sharing folders with a guest Windows 7!

Problem:
So no, what is working? Well, you set the folder (s) in the "Shared Folders" dialog box of the virtual machine settings and will not appear in Windows 7, it works with Windows XP.

The solution:
As many of you out there, I searched and searched online for a solution to this issue, I have also observed to be very popular (why should it be? To create something in the virtual machine and want to save, right?) , and many guides are incomplete or pointing in the wrong direction. So today I present a step-by-step (with screenshots) of this easily fixed issue (you will not believe how easy it was at the end).

For this tutorial, we used VirtualBox 3.0.6 and New Windows 7 Ultimate in Ubuntu 9.10 machine Alpha 6. The steps below assume you have NO shared folders added to your Windows virtual machine 7. If you configured the folders, just follow the three steps!

1. Open VirtualBox, and with 7 virtual machine window, select on the left side, click the button 'General' tab "Details".
2. In the configuration window that appears, click on "Shared Folders" entry (top) and then click the folder icon with a little + (right) to add a new shared folder.
3. A new dialog appears, called Add Share. Click the arrow in the "Folder Path" and select "Other". Find the folder you want to share with the virtual machine of Windows 7 and click OK.
4. You will now see the full path to the folder you want to share; you can give a name or just leave it alone. Click OK to close the "Add Share" dialog.
5. You will now see the folder in the "Shared Folders" section. Click OK to close the settings dialog.
6. Now, start the Windows 7 virtual machine. When the system is fully loaded, open My Computer and click on the "Map network drive" button.
7. In the new window that appears, select a letter in the field of "Drive" (any letter you want from the list), and ... Here is the big secret ... type \ \ vboxsrv \ followed by the name of the shared folder in the folder "field"!

Also, do not forget to check the "Connect with different credentials" option.
After this, click the "Finish" button and you will be prompted to insert the username and password of your Linux machine. Check the "Remember my credentials" option and click the OK button.
