Unity Pro (*.stu) - Working file used during development of the application. This is the most complete file (binary, source application and database are included). The application can be saved even if it is not “generated”.

Unity Pro (*.sta) - Archive file is used to send the application by email or to store on the PC. This file does not contain the database, so the STA is smaller than the STU file. 

This file is used to migrate your application from an older Unity version Vx to a newer Vx+1.

Unity Pro (*.xef) - Openness file in xml format. This file only contains the source code of the application. In a similar manner as the STA file, when you open an XEF file, the database has to be created but the application is not “generated”. A "rebuild all” and a complete download of the application is required. This file does not contain the DTM source code.

Unity Pro (*.zef) - contains the XEF and in addition the DTM configuration source code
