... and to share files between real and virtual machine (in my case, WinVista and WinXP respectively) using VirtualBox, do the following:
- Go to the virtual machine. In the window, up in the VirtualBox menu, Devices and then select "Install Guest Additions." Install.
- In the virtual machine settings, go to "Shared Directories" folder and choose the real machine to be shared.
- Now when it restarts the virtual machine (WinXP in my case, remember), click the right mouse button on "My Network Places" and choose "Map network drive." In Folder, put Browse, and go to "VirtualBox Shared Folders", where you have to choose the shared folder.
