Examining LogicalFiles

On a more earthly note, GAT allows one to examine a LogicalFile instance. In particular, one can determine which physical files, in other words File instances, are represented by this LogicalFile instance. This is extremely useful for the case in which one obtains a LogicalFile instance from a third party, especially if they are ``shady,'' as one can never really know what physical files are represented by a stranger's LogicalFile instance unless one looks.
