Step 1. Install QuickTime Player

The first step is to check if the computer has the QuickTime Player program installed. The easiest method is to use the system search engine by entering the program name QuickTime Player in it.

Programs to open QTCH file

Remember to download programs supporting QTCH files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of QuickTime Player with QTCH files

If the application is or has been freshly installed, but the QTCH file still does not use the QuickTime Player program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. Changes can be made using the "Change" button. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. Checking the "Always use the selected program ..." box will permanently associate the QTCH file with the QuickTime Player program.

Step 3. Update QuickTime Player to the latest version

If, however, after binding QuickTime Player with QuickTime Cache Format there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Apple, Inc. page and install.

Step 4. Check for the following problems with the QTCH file

Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:

The affected file may be 0 KB or smaller than expected. Usually this applies to QTCH files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file QTCH or the program directory. As a result of the scan, sometimes it is not possible to recover QTCH files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the QTCH files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair QTCH file corruption. You can restore the file from a backup or use Apple help.
The program indicates that the file is encrypted or corrupted. The encrypted file QTCH except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. The problem is only writing to the file, not reading it. It is best to move QTCH to a different directory.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
