What is a .QPX file?
The file extension .QPX is associated with the QuickTime Player, which is a multimedia software developed by Apple. This type of file is known as a QuickTime Player Extension. Essentially, what a .QPX file does is it adds more capabilities to the QuickTime Player. For example, it allows the player to support and play additional video formats that it couldn't handle before. This means if you have videos in formats that QuickTime Player originally couldn't play, installing a .QPX file could enable the player to support those formats.
To open a .QPX file, you need to have Apple QuickTime Player installed on your computer. QuickTime Player is included with the macOS operating system, so if you're using a Mac, you likely already have it. Once you have QuickTime Player, opening a .QPX file usually involves the file being automatically recognized and utilized by the player to enhance its functionality, rather than you opening the file directly like a video or document file.
In summary, a .QPX file is used to improve and expand the capabilities of Apple's QuickTime Player, allowing it to play more types of video files. You need to have QuickTime Player, which comes with macOS, to use .QPX files.
