What is a .PXX file?
A .PXX file is a type of secure file used by Keyman Developer, a software program designed for creating and sharing digital keyboards for various languages. This file is encrypted, meaning it is protected to keep its contents safe and private. It specifically stores details about how the user interface of a custom keyboard looks and functions. This information is compiled from another file type called a .KCT file, which is the source file where the keyboard's design is originally created.
To open a .PXX file, you need to use Tavultesoft Keyman Developer, the same program used to create it. This ensures that the file and its contents are handled correctly and securely.
When you use Keyman Developer to make a new digital keyboard, you can share this keyboard with others. The .PXX file is a part of this sharing process. It is important to note that the .PXX file should not be shared by itself; it is meant to be included with the complete keyboard package, typically alongside an .MSI file in the project's output folder. This .MSI file is the installer package for the keyboard.
Additionally, the .PXX file is specifically linked to the installer it was created with. This means you cannot use the .PXX file with any other Keyman product or installer other than the one it was originally designed for. This locking to a specific installer helps maintain the security and integrity of the custom keyboard setup.
