Notes about the PDXAB 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 PDXAB file type is primarily associated with 'Europa Universalis III' by Paradox Interactive. Europa Universalis III is a grand strategy game by Paradox Interactive, covering a period of time from the collapse of the Byzantine Empire in 1453 to the French Revolution in 1789.
