How to open DQY file?

The most common problem when using Excel Query Format is that a specific DQY is not associated with the program. Thus, when you open DQY, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the DQY 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 Microsoft Excel

The first step is to check if the computer has the Microsoft Excel program installed. To do this, enter the name Microsoft Excel into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file DQY with Microsoft Excel. Below you will find a list of applications that support DQY files.

Programs to open DQY file

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

Step 2. Create association of Microsoft Excel with DQY files

However, it may happen that the application itself does not cause the DQY file to open in the Microsoft Excel application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. 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 DQY file with the Microsoft Excel application.

Step 3. Update Microsoft Excel to the latest version

The fault may also lie with the Microsoft Excel program, it is possible that Excel Query Format requires a newer version of the program. This can be done using the application (if it provides such options) or from the Microsoft Corporation website and install the latest version.

Step 4. Check for the following problems with the DQY 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. This suggests truncating the DQY file contents when downloading or copying. The only repair option is to download the file again.
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. The scan should cover the entire computer, not only the DQY file that we want to open. However, remember that not every infected DQY file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the DQY files changes over time. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular DQY file corruption. The easiest way to restore the file is from a backup or by contacting Microsoft, but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted DQY 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.
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. Copying the DQY file to another location will fix the problem.
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. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the DQY file for a certain period of time. If the problem persists, restart the machine.
