The dia file extension is associated with the Psion Organiser CM/XP Format for OPL (Organiser Programming Language).

OPL is a quite powerful compiler language. This means that the source code (what you type in) is first translated into a kind of machine code and can then be used like a built-in application.

The dia file stores data for Psion Organiser diary.

How to convert:

As far as we know, this .dia file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
