Briefcase files

I am a new user and i'm trying to create a briefcase file from my desktop to my laptop. On each attempt, it will copy the files into the briefcase directory but then when I go to update the files, I am notified that all files are orphaned files and no update will occur. Suggestions?

Not sure, I've never used MS briefcases... but this is happening only with Dopus? It works with Windows Explorer?
