FileName( <file type> ) 

The one optional parameter, <file type>, allows the script writer to display only files of a particular kind, such as text files or applications.  Typical file types are "STAK" for HyperCard stacks, "TEXT" for simple text files, and "APPL" for applications.

Unfortunately, sources for the names of other file types is limited  without access to utilities such as ResEdit or MacSnoop.
