The Pack Application tool has a new feature: "Include Input Data Files":
Selecting this option will read the PFF for your application, if one exists, and include in the zip file the input data files that are referenced in the PFF. If you are running a large data entry operation with many data files, this may be of limited use, but if you are entering data for a small survey, you may only have one data file, and this option allows you to easily encapsulate all the important files for your application.
