This article covers the settings for ETS project import and export. These settings can be defined via 'Import/Export' entry within the 'Settings'.

Project Export
Include Catalog Information
When enabled, the project specific product (catalog) information will also be part of the project export (this obviously increases the size of the exported project file).
This even involves products removed from the project.
Include Compatible Application Programs
When enabled, any compatible Application Program per product used in the project will also be part of the project export. This makes it possible to change the Application Programs once the project has been imported (and opened).
Include Relevant Device Configuration Apps
When enabled, the project specific DCAs will also be part of the project export. This also includes data that DCAs have stored locally for the project. All related DCA binary files (.etsapp) will be stored within the 'Project Files' (within the project properties).
DCA (functional) settings are not included in the project export.
Project Compact
Compact project store on export
When enabled, any cached product related data not used in the project, will not be included in the project export.
Compact project on ETS Inside transfer
When enabled, any cached product related data not used in the project, will not be included in the project export, and hence not transferred to the target ETS Inside server.
