I still receive a CRC error on the attached file:

$ unzip -t ins-0534-2008_test.zip
Archive: ins-0534-2008_test.zip
error [ins-0534-2008_test.zip]: missing 1 bytes in zipfile
  (attempting to process anyway)
error [ins-0534-2008_test.zip]: attempt to seek before beginning of zipfile

  appropriate BINARY mode and that you have compiled UnZip properly)

At least one error was detected in ins-0534-2008_test.zip.

This may be an artifact of using Outlook/renaming the file to .txt...

Hrm... when run via your shell, is it calling the same unzip program that incron is calling?

One thing I noticed---are you sure you want incron to use the IN_CREATE event? incron may be calling your scripts before the file has finished writing (hence the incomplete zip file error).

Try IN_CLOSE_WRITE. This event will cause incron to act only when a file being watched has finished writing.
