live.pirillo.com - My hard drives, much like yours, are full of files collected over the years. I've used every operating system you can think of. Sometimes, I create files that are only available for one operating system or another. This, of course, creates headaches at times. How do I deal with this? OS X is my primary operating system now, and there are thankfully several free programs available for a Mac that make accessing and using my Windows files much easier.
