You're here because you have a file that has a file extension ending in .eap. Files with the file extension .eap can only be launched by certain applications. It's possible that .eap files are data files rather than documents or media, which means they're not meant to be viewed at all.

An Enterprise Architect project file can be created, opened and edited using the Enterprise Architect software, and this application saves these project output files in the EAP format, which is a file affixed with the .eap extension. The Enterprise Architect program and the EAP file format were developed by Sparx Systems to offer users with functionalities for designing and formulating custom software systems. Classified as a Computer Aided Software Engineering (CASE) application, the Enterprise Architect program and the EAP file format are implemented with support for UML 2.0 standards and specifications. The Enterprise Architect software can be installed in computers running on Microsoft Windows-based systems to start creating, opening and modifying the content of these EAP project output files. The data stored in an EAP file include source code and developer comments entered by the author of the EAP project output file. These pieces of data is referenced by the Enterprise Architect software when a user opens and views the content of the corresponding EAP file with this application.

Launch a .eap file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .eap file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .eap files aren't yet associated with it. In this case, when you try to open a .eap file, you can tell Windows which application is the correct one for that file. From then on, opening a  .eap file will open the correct application.

Be careful not to rename the extension on .eap files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

A file extension is the set of three or four characters at the end of a filename; in this case, .eap. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
