What is "qtch"

qtch (.qtch) is a filetype used by QuickTime to store audio or video files streamed from a server on the client's computer hard drive.

The first 16 bytes are:

<nowiki> Hex ; ASCII 00 00 00 50 71 74 63 68 00 00 00 02 00 00 00 02 ; ...Pqtch........ </nowiki>

This file type seems to have been introduced with QuickTime Player 7.x. The file is normally stored in any sub-directories of the following location:

C:\Documents and Settings\\Local Settings\Application Data\Apple Computer\QuickTime\downloads

E.G.:

C:\Documents and Settings\Administrator\Local Settings\Application Data\Apple Computer\QuickTime\downloads\08\02\82580278-44f0f184-c8c435b8-526b4f79.qtch
