Notes about the OUX 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 OUX file type is primarily associated with 'PCCharge' by VeriFone. PCCharge software turns any PC or PC-based POS system into a secure payment-accepting and processing device without interfering with other programs.
