My Documents and Department File Shares (aka: "Matthew") are the two primary Network File Share types on campus.
My Documents is the personal folder that each Faculty and Staff member has. Department File Shares are a collection of intra- and inter-departmental shared folders of documents accessible on the campus network.
Network file shares allow you to access files directly and work on them as if they were stored on your local computer. My Documents is generally used as a default storage location for an individual's files that don't need to be shared. Department File Shares are where files that need to be shared across multiple users can be stored.
