An EX file is a source code file written in the Euphoria programming language, a general-purpose procedural language. It may contain all the source code for a program or may be one of several Euphoria source code files in a programming project.
The Euphoria programming language is an easy-to-learn language that was introduced in 1993. It was released by Rapid Development Software and became open source in 2006, now being maintained by openEuphoria Group.
NOTE: The programming language, which is stored in EX files, can be used to develop programs for Windows, Linux, FreeBSD, and MS-DOS.
