What Is an EAP File?

How to open, edit, and convert 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 are used to store exposure, offset, and gamma correction values for Photoshop images. The values are controlled within Photoshop's Image > Adjustments > Exposure menu.

If it's not in either of those formats, it might instead be a C-more Project file associated with programming software from AutomationDirect.

EAP is also short for some technology terms that have nothing to do with these file formats, such as Extensible Authentication Protocol and external auxiliary power.

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 file in Enterprise Architect, 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 menu from that screen and select Load Preset to browse for the file.

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

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. They're stored in the \Presets\Exposure\ folder of the program's installation directory, making this another way to use them—just copy them to this folder and restart the program.

In Windows, this is most likely the full path:

C:\Program Files\Adobe\Adobe Photoshop\Presets\Exposure\

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 doesn't have its own graphical user interface. You can find the user guide here.

C-more HMI programming software from AutomationDirect is needed if your file is in that format.

If you find that an application on your PC does try to open the file but it's the wrong application or you'd rather have another installed program open it, 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 EAP to PDF with the FILE > Print to PDF menu. Another supported conversion is 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 file in a different file format, it would change its file extension and structure, and prevent Photoshop from using it.

C-more has a File menu you can use to save the project to a different file format. The program supports other files like EAP9, EPP9, EAS9, and EAS, so you might be able to convert your project to those formats.

Still Can't Open the File?

Keep in mind that some files just look like this one 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 mentioned above.

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