Information about the .cxt (cxt) file type

Below is all the information we have available on file about the .cxt (cxt) file type.

.cxt
Macromedia Director protected cast resource file. These files are not editable and are for distribution with a movie (.dcr) file.

.cxt appears to have been used by older version of Macromedia Director. Modern versions of Adobe Director (Adobe having acquired Macromedia) use .cct files. 

Where this is available we would like to include file format information on .cxt files, as well as information on how to view or open files of type .cxt. If you know of any information which we have missed then please let us know.
