The media you work with can reside anywhere on the network. When you import media, you are not physically copying that media to another location, but rather you are creating a composition for that media in Composite; the actual physical location of the media is stored as information in the composition. Composite recognizes both drive letters and Universal Naming Convention (UNC) paths. Composite also supports Wiretap—see Accessing the IFFFS Libraries on the Network Using Wiretap.
