The Briefcase feature in Windows XP helps you keep your files updated by automatically synchronizing multiple copies of individual files. In other words, Briefcase keeps track of the relationship between files on two or more computers. For example, if you use a desktop computer at the office, and you use a portable computer when you are on the road, Briefcase synchronizes and updates the files on your desktop computer to the modified versions when you reconnect your portable computer to the desktop computer.

Briefcase stores and displays the update status of files. It keeps track of whether a file is linked to the original file on your main computer, or whether it is an orphan file (a file stored in Briefcase that is not linked to another file). You can use this information to keep your files organized and to keep track of the most recent versions of your files.

Use Briefcase when you use two or more computers to work on files, and when you need to frequently transfer files between computers by using a direct cable connection or a removable disk.
