I don't know much about linux. The location tab is for folders that are used by the OS. Example, if you want to save a pic from the net, windows will want to use the 'Pictures' folder. If you have moved the folder by the drag and drop method rather than through the 'Locations Tab', Windows won't know where it is. If you drag and drop the Contacts folder to another place without using the locations tab, Windows Mail will not know where to look for email addresses. If I remember right, some if not all of these folders will be recreated on reboot. Then if you right click an email and click 'add sender to contacts' it will go in the new folder and not the one you moved. Dragging and droping the personal folders (as I did in Win2k), to my E:\ drive was my first big mistake when I started using Vista.
