File Based Repositories


In the Desktop and Professional editions of Enterprise Architect, you create Enterprise Architect projects as .eap files. If you prefer, you can also create your projects as .eap files in the Corporate and suite editions of Enterprise Architect.

A default project file (EABase.EAP) is supplied in the Enterprise Architect installer and is automatically stored in your Enterprise Architect installation directory; you can copy this as the base for your own projects. You can also create your own base projects, and copy existing operational projects.

Copy Existing Project

A Base project contains templates and reference data to enable you to develop your own project quickly

You can also copy an operational .EAP project file to enable separate development by team members, or to create an evaluation or distribution version of the project
