The pdxa file extension is associated with Europa Universalis III, a computer game developed by Paradox Interactive. The file is part of the game's native data used to support its operation.
Europa Universalis III reads pdxa files from the appropriate game installation or data location. The format is specific to the game and is not intended as a general-purpose document or data-exchange format.
On Microsoft Windows, install and run Europa Universalis 3 to use a pdxa file. The game should read the file automatically when it is stored in the location expected by the installation.
There is no need to open a pdxa file in a text editor, and changing or moving it may prevent the game from working correctly.
A pdxa file generally cannot be usefully converted to another format. It is a native Europa Universalis III game data file.
