Compact a Project

After some time, a project .EAP file might benefit from compacting to conserve space.


  • Compacting shuffles the contents of the model around, eliminating unused space and generally reducing the size of your model file.
  • In the Corporate, Business and Software Engineering, System Engineering and Ultimate editions of Enterprise Architect, if security is enabled you must have Administer Database permission to compact a project.


Always compact and repair projects on a local drive, never on a network drive.

To compact a project, follow the steps below:

  1. Ensure that no users have the target project open.
  2. Select the Tools | Manage .EAP File | Compact .EAP File menu option.
  3. Follow the on-screen instructions to complete the process.
