Parallels has released a new release candidate of Parallels Desktop for Mac. The major changes in RC3 (Build 3170) include the ability to upgrade seamlessly from Windows XP to Windows Vista. New options to drag-and-drop make it even more secure.
In RC3. When you drag-and-drop a file for the first time, you’ll be prompted if you’d like to enable “local” or “global” file sharing. Here’s the difference: Global Sharing shares the your entire Mac file system (DISABLED by default); Local Sharing shares only your Home folder.
