I run Vista via boot camp (I only use it for games) and I have a problem. I have an file on my Mac desktop that I want to get onto Windows. It's approx. 5.4gb. My largest recordable DVD is 4.7gb and my LaCie hard drive can't work with both Mac and Windows. I tried dragging the file into the Windows partition hard drive which appears on my desktop, but it says that it cannot be modified. Any way around this?
