I've recently installed Parallels Desktop 6.0 on my MacBook Pro and I'm running Windows 7 on my virtual hard drive. I noticed that approximately 70GB of my MacBook 500GB hard drive has been allotted to my Windows virtual drive. It is possible to increase the amount of virtual hard drive space allotted to Windows by changing the settings somewhere on Parallels Desktop 6.0? If so, how is this done? Also, is it necessary to increase the size of the virtual hard drive space if I've only got about 10GB of space remaining after loading software? In other words, would Windows run more smoothly if I had some more virtual hard drive space available? Thanks in advance for your help!
