What is QHC file?
The file in the QHC format belongs to the Settings Files category. It was designed by Digia Oyj. In addition to this file, the Settings Files category includes 1305 related files. Qt Help Collection is supported by 1 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Windows. It is recommended to use Qt SDK to handle this file. This is a program created by Digia Oyj.
How to open QHC file?
The main problem with Qt Help Collection is that the QHC file is incorrectly associated with programs. This causes the file QHC 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 QHC 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 Qt SDK
An often overlooked issue is to make sure that Qt SDK is installed on the computer. The easiest method is to use the system search engine by entering the program name Qt SDK in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open QHC files.
Programs to open QHC file
Remember to download programs supporting QHC files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Qt SDK with QHC files
If, despite the installed application, the QHC file does not start in the Qt SDK 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 displayed window will contain information about the program that supports this type of file. Changes can be made using the "Change" button. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the QHC file with the Qt SDK application.
Step 3. Update Qt SDK to the latest version
The fault may also lie with the Qt SDK program, it is possible that Qt Help Collection requires a newer version of the program. Some applications allow you to update from the program level, and for others you need to download the installer from the Digia Oyj page and install.
Step 4. Check for the following problems with the QHC file
Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:
Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the QHC file. The only repair option is to download the file again.
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. However, it is important to scan the entire system, not only the file QHC or the program directory. As a result of the scan, sometimes it is not possible to recover QHC 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 QHC 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. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair QHC file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Digia Oyj
When reading, a message appears that the file was encrypted or corrupted. The encrypted QHC 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 of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move QHC 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. Just close unnecessary programs. Sometimes you have to wait for the session to the file QHC to close. However, some background programs may block the QHC file while scanning. If this does not work either, restart the device.
