    This interface displays a list of files in a treebox.
    Inherits from: nsISupports Last changed in Gecko 1.7

    Note: nsIFileView is Linux-only interface. It's not included in Windows or Mac builds.

    Note: A quirk of the nsIFileView is that it requires an appropriate treecols section in the tree tag, by default fileview will return the file size in the column. If the treecol id is "FilenameColumn" fileview will return the file name, if the id is "LastModifiedColumn" it will return the date of last modification. Currently no other file stats are implemented.

    The nsIFileView provides a configuration interface to;1 , which also implements nsITreeView so that it can be passed as a tree view.

    Implemented by:;1. To create an instance, use:

    var fileView = Components.classes[";1"]
