Extension: QTCH
Program and/or Extension Function [What's This?]		Company [What's This?]
Quicktime Cached File		Apple Inc.
Specific Notes [What's This?]
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.

General Info

• If the extension you are looking for is of the form .??_ the file is likely a compressed file and part of an install routine. When the install program runs it will expand the file and replace the underscore with the proper letter for the file type.
• If the file is sent as an audio file with any three-character extension it may be a dictation file where the extension is the dictator's initials; playable by BCB Voice Systems software (see ??? extension). The file could likewise be a dictation file in TrueSpeech format. Use Windows Sound Recorder and/or Media Player to play these back.
• If the extension you are looking for has a number at the end or is only a number and there were no results consider entering the same extension format using zero or one as some programs produce numbered split files but when the split can be extensive (e.g., .000-.999) only the first entry is in the database.
