if you look around various places, youll find the mac copy of norton utilities 2, it contains a program called norton backup.
From here, you could backup your entire hard disk into a norton backup image. Then you can boot your emulator with a boot disk/CD, run norton backup, and "restore" the image onto a virtual hard disk file for the emu.
There are probably easier ways, but this way works too.
Method 2 is to create a disk copy image big enough to hold everything, drag it all into there and save the image. The image could then be open and copied all back of in the emulator. But norton backup will restore your file structures and your desktop file as well.
