What is a QTCH file

QTCH files mostly belong to QuickTime. The QTCH file is used as a QuickTime cache file.
It stores temporary media data to speed up video playback in QuickTime.

This file helps manage streaming by keeping parts of the media ready for quick access.

It is created and maintained automatically by QuickTime, so manual editing is not needed.

On rare occasions, QTCH can also refer to a QuikTrip Kitchen Customizer file.

Programs that open and convert QTCH files:

QuickTime
See the previous paragraphs to learn more about the main application. QTCH files are often referred to as QuickTime data files because this type of file is primarily created or used by this software.
Quicktime (Cached File) by Apple Inc.
This is a cached file but not compressed. If you know the original file format, add the appropriate file extension to the file and it should play in whatever player you use for that format (or in Quicktime). If you don't know the format, see if TrID can identify it for you. iTunes uses this format as well but Apple changed the way these files are handled and they are scrambled in some fashion so you can't just put a new header on the file and get the original media as you could under Quicktime. Also, TrID will not identify the media type; only that this is a Cache file. You could use a packet sniffer to search for the file type of the data stream as it is downloaded but you will still have to manually construct a new header for the file. The identifying characters used for this association are - Hex: 00 00 00 50 71 74 63 68 00, ASCII: Pqtch . Related links: TrID, Wikipedia QTCH Page

QTCH file format details:

To view or edit QTCH files you need to know the file format, because it determines how the data in this file is stored. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. File extension, signature and file format must match; otherwise errors will occur when the file is opened. Knowledge is power - this also applies when dealing with unknown or faulty files. In the following you will find our evaluation of the QTCH files:

QTCH is not a common file extension and is mainly used by one program with a specific format.

100% of all QTCH files are Quicktime Cached data files. They consist of unreadable binary data. Most of these files are 1 KB to 15 MB in size. This is an old file type which is rarely used today. Certain words are almost always found in the files, such as Pqtch.
