How to open QTP file?

An often recurring problem with QuickTime Preferences Format is that QTP is not associated with the correct program file. This causes the file QTP to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the QTP file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install QuickTime Player

The first step is to check if the computer has the QuickTime Player program installed. This can be achieved by typing QuickTime Player into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open QTP files.

Programs to open QTP file

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

Step 2. Create association of QuickTime Player with QTP files

If, despite the installed application, the QTP file does not start in the QuickTime Player application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can set the program to handle this type. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the QTP file with the QuickTime Player application.

Step 3. Update QuickTime Player to the latest version

If, despite the association of the QuickTime Player program with the QuickTime Preferences Format file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Apple, Inc. website or update the program from the application.

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

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

The QTP file may be unusually small compared to the original file. This is most often caused by a problem while downloading the QTP file. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the QTP file that we want to open. Sometimes virus-infected QTP files cannot be recovered, so make a backup in advance.
Older version of QTP file may not always be supported by the latest software version. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair QTP 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 QTP 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.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the QTP file to another location.
This can happen on a file that does not support multiple access. Some file types can only be opened in one program at a time. Closing other programs should help. Sometimes you have to wait for the session to the file QTP to close. 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.
