How to open QCN file?
The most common problem when using Qualcomm QPST Drive Backup is that a specific QCN is not associated with the program. This is manifested by the fact that QCN files open in unusual applications or do not have an assigned program. This can be quickly resolved by following the instructions below.
The first thing you should do is just "doubleclick" on the QCN 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 Qualcomm Product Support Tools
The first step is to check if the computer has the Qualcomm Product Support Tools program installed. The easiest method is to use the system search engine by entering the program name Qualcomm Product Support Tools in it. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support QCN files.
Programs to open QCN file
Remember to download programs supporting QCN files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Qualcomm Product Support Tools with QCN files
If, despite the installed application, the QCN file does not start in the Qualcomm Product Support Tools application, you must create a file 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. Using the "Change" button we can select the desired program. 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 QCN file with the Qualcomm Product Support Tools program.
Step 3. Update Qualcomm Product Support Tools to the latest version
If, however, after binding Qualcomm Product Support Tools with Qualcomm QPST Drive Backup there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the QUALCOMM Incorporated website and install the latest version.
Step 4. Check for the following problems with the QCN file
The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:
The affected file may be 0 KB or smaller than expected. Usually this applies to QCN files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The operating system may be infected with a computer virus. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the QCN file that we want to open. Sometimes virus-infected QCN files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the QCN 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 the failure. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair QCN file corruption. You can restore the file from a backup or use QUALCOMM Incorporated help.
The program can also signal the fact of encryption. The encrypted QCN files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. 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 QCN file to another location.
This problem only occurs with more complex files. In this case, the QCN file is blocked by the first application to open it. Just close unnecessary programs. 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.
