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.

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.
