QTR files are specifically designed for QuickTime Player. Files with these extensions actually contain the resource fork or the structured data to be used by the player. Resource fork is native to Macintosh computer systems. QTR files are closely associated with QTX files which are also used to support information for codecs and other file importers.
Aside the player itself, QTR files can be accessed by another Apple application called the Rezwack tool. This application can be used to integrate both the QTX and QTR files into a single file with QTX extension. Combining both extensions provide flexibility to the product instead of shipping it with both files present.
