The scenario briefcase was designed for is the combination of

an office computer and a portable one. You connect the two

before leaving your office, create a briefcase on the portable

(if you don't already have one on it), then copy the files you

want to work on while away into the briefcase. You can at

this point disconnect the two computers, take the portable

with you and work on the files in the briefcase at home or on

the road. When you get back to your office the briefcase

utility can automatically update the files you changed on the

office computer.
