The QPX file extension is associated with Apple's QuickTime Player. A QPX file contains a QuickTime add-in that the player can load as part of its extension system.
QPX files were used with Apple QuickTime for Windows and Apple QuickTime for Mac on Mac OS X and macOS. They are software components, not media files intended for independent playback.
QuickTime and its extension system are legacy technology. Current operating systems and media players may not support older QPX files, even if the files remain on a computer.
A QPX file is normally loaded by the compatible version of Apple QuickTime rather than opened directly. On Windows, use the version of QuickTime for Windows for which the extension was designed; on Mac, use the corresponding QuickTime for Mac installation.
Modern versions of Windows and macOS may not run the required legacy QuickTime software or load its extensions. Do not rename the file as a media file, because a QPX file is not a video or audio recording.
QPX files are QuickTime extensions, not media files, so they cannot be meaningfully converted to a video, audio, or document format.
If the extension provides a required feature, the practical option is to use a compatible QuickTime installation or find a current replacement for that feature. The QPX file itself has no normal export format.
