There are some lock files in the VMWare fusion bundle. Right click, and select, Show Files. That is where everything is stored. BUT it will not get you the files on the virtual hard drive, it will just get you access to the VMWare image files (including the hard drive image but that is not a standard image file).
I've had VMWare crash once or twice where it left my XP in a bad state. There are ways to reset it and get it to work again. The VMWare forums is where you really would like to be.
Good Luck.
