A feature of Microsoft Windows 95, Windows 98, Windows NT 4.0, and Windows 2000 that is typically used to enable mobile users to copy and synchronize files between a desktop and a portable computer so that they can easily copy and work on files at home or on the road without creating version conflicts.
Using Briefcase is simple. Create a Briefcase icon by right-clicking the desktop, choosing New from the context menu, and then choosing Briefcase. Then drag the files you want into the Briefcase folder and copy it to your laptop computer.
After you modify the copies of the files in your laptop’s Briefcase folder, connect your laptop to your desktop computer and the newer versions will be copied over the old.
If the original files on the desktop computer were modified while you were away, you will be prompted to specify which modified version is the correct one for each file. (Briefcase cannot merge changes in files.)
