/**
 * A representation of a File object when the file is no longer accessible. For example, an applet
 * may collect information about files on a user's system. Analysis of these files may be necessary
 * once the results are sent back to a server. In order to do so, certain file characteristics need
 * to be burned in (such as whether the file is a directory).
