Notes about the EXU file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The EXU file type is primarily associated with 'Euphoria' by Rapid Deployment Software. Euphoria is an interpreted programming language for computers running MS-DOS, MS Windows, Linux, and FreeBSD. The U at the end indicates this is likely a program written by/for the Linux version.
