Share Files between Windows and Mac OS X in VirtualBox

When you installed the Guest Additions, you added support to Windows for sharing folders with Mac OS X. Before you can use this feature, you must turn it on and configure it, as follows:

1. If the Windows virtual machine is running, shut down Windows.
2. Select your virtual machine, click Settings, and click Shared Folders on the toolbar

   
   

   Figure 9-8. Use the Shared Folders pane of the Settings window to add shared folders to your virtual machine.

   
3. Click the Add Share  icon. The Add Share dialog appears.
4. From the Folder Path pop-up menu, choose Other. Navigate to the folder you want to share (such as ~/Desktop) and click Choose.
5. Make a note of the name in the Folder Name field (or change it, if you prefer). Click OK to dismiss the Add Share dialog.
6. To designate other shared folders, repeat Steps 3 through 5. When you’re finished, click OK.
7. Start the virtual machine. After Windows starts up, choose Start > (My) Computer.
8. In Windows XP, choose Tools > Map Network Drive; in Windows 7 or Vista, click Map Network Drive at the top of the window. In the Folder field , type \\vboxsvr\folder-name (replacing folder-name with the name you noted in Step 5). Click Finish. (Repeat this step, if necessary, to map additional shared folders.)
