I have a desktop running XP and a laptop running Vista. I want to use a usbdisk to contain a copy of the My documents folder I want the My documents folder to be sync'd with both systems. I have a problem with Vista in that I can't run synctop as administrator. and some files on the usb drive can not be overwritten by synctoy on vista. I also had a problem removing a folder from the usb drive that was created on the XP on the Vista system. What the heck do I have to do to get this security stuff working. I knew I should not have bought the laptop with Vista on it. I can't say here what I really think of Vista. My 825MHz laptop runs things faster than this new 2ghz dual core laptop.
