Psion OVAL control data
File type: Various data file
The ovx file extension identifies control data used by Psion OVAL, an application development language for Psion devices.
An ovx file is associated with the design and development of OVAL applications rather than being a standalone document.

OVAL stands for Object-based Visual Application Language. It was a Psion programming language with an approach similar to Visual Basic, used to create applications for Psion's handheld computing platform.
The ovx file contains control data used while designing Psion applications with OVAL. It is part of the OVAL development environment and may need to be kept with the other files belonging to the relevant application project.
Psion OVAL and the ovx file extension are obsolete, so the format is not normally used by current software.
Open an ovx file with the original Psion OVAL development software in a compatible Psion environment. It is not generally supported by modern desktop applications.
If the file belongs to an old OVAL project, open it from that project rather than treating it as an independent document.
The ovx file contains development control data rather than a conventional document, so direct conversion to a modern general-purpose format may not be available.
To migrate an old OVAL application, the application and its data generally need to be recovered in the original OVAL environment and recreated or exported using a suitable replacement system.
