I have configured our iFolder server (OES2/SP2) to exclude certain file types. I don't see the need to replicate someone's iTunes library on our business servers.

A small number of users were connected to the server before the exclusions were put in place. I've manually added the exclusions to the users, but I still see excluded file types in their storage folder on the server. Is it safe for me to remove the files at the server? I don't want the music and movies replicated, but I don't want to do something that will cause them to disappear from the workstation.
