.RPPRJ File Extension

Shared project created by Axure RP, a prototyping and wireframing application; saves a diagram that can be shared, annotated, versioned, and iteratively upgraded during the design process; often used for creating mockups of user interfaces.

Shared projects are different than regular Axure RP projects (.RP files). Shared projects allow the project file to be stored on a shared network drive or in a Subversion version control repository for collaborative development.

You can create a shared project by selecting File → New Shared Project.... You can also begin using an existing shared project by selecting File → Get and Open Shared Project....
