A PP7 file is a file that contains all the information PlanetPress Design requires to convert and execute the document. It includes a description of the visual layout of the document, the sample data file, the PPD for the document, all the static images for the document, and all page and document attachments.
By default it also includes the sample data file.
You create a PP7 file for a document the first time you save the document. You can also set a password on a PP7 file.
