Project Size of Enterprise Architect files
The maximum size of Enterprise Architect Project files has yet to be reached by any of our users, although we are aware of some users testing Enterprise Architect Corporate Edition with a SQL Server Repository having a file size just below 1.4 GB (1390.50 MB). Even when using files of this size, it was reported that Enterprise Architect remained responsive and usable with the speed being determined by the capability of the user’s hardware.

The .EAP file structure affords the user with a maximum file size of 1 GB ensuring that even the largest practical project can be supported with this file format.

Unrecognized Database Format
Some users receive an error message "an error has occurred: Unrecognized database format <file path here>", when attempting to open .EAP files. This is caused by attempting to open an Access 2000 or higher .EAP file while Enterprise Architect is set for Jet 3.5.

To open the Access 2000 .EAP, file go to Tools | Options and check the "Use JET 4.0 - requires restart" checkbox. Then close Enterprise Architect and restart the application for the new setting to take effect.

Corrupted .EAP file
Unfortunately on rare occasions usually caused by network or PC outages a .EAP may become corrupted and may not be opened. To alleviate this situation the user should copy the corrupt file to a local directory , then make a backup copy of the file. The next step is to open Enterprise Architect, but when prompted to open a project to press cancel. Next go to the Tools | Manage .EAP File | Repair .EAP File from the main menu. The user should then follow the prompt and select the file for repair.

For more information on repairing corrupt .EAP files go to the Repair a Project Page.

Database Repository Supported Types
An Enterprise Architect model is stored in a database and Enterprise Architect supports a range of DBMS products, listed here.. All database supported types other than MS Access require the Corporate Edition of Enterprise Architect.
