Briefcase is a tool that allows mobile users to easily track and update copies of files stored on two or more computers— usually an office computer and a portable computer. Users put the files that need to stay in sync into Briefcase before going on the road. When users return, connectto the network, and open Briefcase, Windows 95 prompts them to synchronize the files. Briefcase then updates the file on the network to match the file on the portable computer.
