What Is an EAP File?

How to open, edit, and convert EAP files

EAP Files
EAP Files.

A file with the EAP file extension is most likely an Enterprise Architect Project file. They're created by the Computer Aided Software Engineering (CASE) tool from Sparx Systems called Enterprise Architect.

Some EAP files may instead be Adobe Photoshop Exposure files. These kinds of EAP files are used to store exposure, offset, and gamma correction values for Photoshop images. The values are controlled within Photoshop's Image > Adjustments > Exposure... menu.

Don't confuse the EAP and EPS formats — EPS files are Encapsulated PostScript files.

How to Open an EAP File

EAP files that are project files can be opened with Sparx Systems' Enterprise Architect program, or for free (but in read-only mode) with Enterprise Architect Lite.

If you're having trouble with your EAP file in an Enterprise Architect application, see their guide on data management tasks like repairing, compacting, or replicating EAP files.

Adobe Photoshop is used to open EAP files if they are Exposure files. This is done through the Image > Adjustments > Exposure... menu. Choose the small Preset options menu next to the OK button and then select the Load Preset... button to browse for the EAP file.

You can also save your own custom exposure settings in Photoshop through the same process; just choose Save Preset... instead.

To install EAP files to Photoshop, copy them to the \Presets\Exposure\ folder of the program's installation directory, and then restart the program. In Windows, this full path is probably C:\Program Files\Adobe\Adobe Photoshop\Presets\Exposure\.

When Adobe Photoshop is first installed, it comes preloaded with a few EAP files by default, called Minus 1.0, Minus 2.0, Plus 1.0, and Plus 2.0.

EAP files are also associated with eaDocX so that you can load EA models into programs like Microsoft Word. It installs as an add-in, so it's not a fully functional program in and of itself and does not have its own graphical user interface. You can find the user guide here.

If you find that an application on your PC does try to open the EAP file but it's the wrong application or if you would rather have another installed program open EAP files, see our How to Change the Default Program for a Specific File Extension guide for making that change in Windows.

How to Convert an EAP File

An Enterprise Architect Project file can be converted to a different file format with the Enterprise Architect software. For example, you can save the EAP to PDF with the FILE > Print to PDF... menu. Another supported conversion is EAP to XMI (XML Metadata Interchange), which is done through the PACKAGE > Import/Export menu.

There probably isn't any reason to need to convert an EAP file that's used in Photoshop because it's just a set of exposure settings that apply to the Adobe Photoshop program. If you did happen to get the EAP file in a different file format, it would change its file extension and structure, and prevent Photoshop from using it.

More Help With EAP Files

Keep in mind that some files just look like EAP files because the file extension is spelled similarly. In other words, you might not even have an EAP file, and that could be the reason it's not opening with the programs we linked to above.

Some examples of files that could be confused for EAP files include EASM, EAS (RSLogix Symbol), EAR (Java Enterprise Archive), and EAL (Kindle End Actions) files.
