Controlling deleted projects
Each *.dpp package is created when the project is deleted or unassigned. Because *.dpp packages are identical to *.dpzpackages, you can restore deleted packages by changing the file extensions from*.dpp to *.dpz. The *.dpp packages are saved in this folder:
C:\Documents and Settings\All Users\Application Data\UNICOM\Intelligence\Interviewer\Archive
Each *.dpp package includes these items:
cache files (*.chj)
case data files (*.ddf)
audit data files
project files
respondent files (images and audio files).
To control deleted projects
1 Edit the IPlayerConsole.exe.config file: see Customizing the Interviewer Console.
2 Set the ArchiveDeletedProject value:
true: *.dpp packages are created whenever projects are deleted or removed.
false: *.dpp packages are not created when projects are deleted or removed.
The default value is true.
  <add key="ArchiveDeletedProject" value="true"/>
