Czym jest plik QPX?
A QPX file is an extension for earlier versions of Apple QuickTime Player, a media player bundled with Mac OS X. It contains information that extends the capabilities of QuickTime Player, such as support for video formats that the media player does not natively support. QPX extensions allowed users of early QuickTime Player versions to customize the media player to handle a broader range of media formats depending on their needs.

QPX extensions function similarly to plugins, which third-party vendors or Apple developed to integrate into QuickTime Player, allowing the software to expand its media playback capabilities without requiring a full program update. The files were typically small in size, so users could more easily add or remove them based on their needs.
QPX extensions were beneficial during QuickTime Player's earlier years in the late 1990s and 2000s when compatibility with emerging media standards and formats frequently required extensions. However, the media player no longer supports QPX files.
Jak otworzyć plik QPX
You can only open QPX files with earlier versions of Apple QuickTime Player. Modern versions of the media player do not support the QPX format.

A QPX file is a query program compiled from a .QPR source code file by Microsoft Visual FoxPro, a database management system. It is the executable version of a database query, containing bytecode that Visual FoxPro runs without needing to recompile the source code. QPX files help improve performance, especially where frequent query execution is necessary, since compiled queries execute faster.
