I would start debugging the code:

  * the easy way: activate Zope logging (--> "doc/LOGGING.txt")
    and add "zLOG.LOG" calls to document the decisions "ExtFile" makes

  * a bit more difficult: debug directly, either with a Python IDE
    (my colleagues use "WingIDE" and are quite happy)
    or with "pdb".

    HowTo on Zope.org.
