Upon setting up my MBP, I put in my name [hard drive, user, ???] and I would like to change it but, not sure how -- When I click on finder, the name is listed at the bottom (on the left) next to the 'house' icon and on a different screen it is after /Users/. After further investigation, I believe it is referred to as my 'home folder'.

I inserted a flash drive formatted for PC [w/PC files] and it shows up as an item I can click but, when I do it disappears. Will a stock MBP not load and 'reformat' the PC files to work on the MBP [e.g. .ODX to .XLS] or do I need additional software to migrate over files? Can I then assume that I need to reformat the USB flash drive for Apple?

Thanks
