Description

Cache of a QuickTime audio or video file downloaded or streamed from the Internet; if the file was created by QuickTime 6.5 or earlier, it may be opened in QuickTime Player by changing the file extension to match the original file (i.e. .MP3, .MPEG, .MOV). QuickTime 7 and later scrambles the header information of QTCH files so they cannot be played back by simply changing the file extension.
