How to open DFQ file?
The main problem with SmartWare Query Definition is that the DFQ file is incorrectly associated with programs. This causes the file DFQ to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.
The first thing you should do is just "doubleclick" on the DFQ 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 SmartWare
In this case, you should first verify that the SmartWare application is installed on the computer. The easiest method is to use the system search engine by entering the program name SmartWare in it. If it is not, installation may solve the problem, as most applications create file associations during installation. Below is a list of programs that support the file DFQ.
Programs to open DFQ file
Remember to download programs supporting DFQ files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of SmartWare with DFQ files
If, despite the installed application, the DFQ file does not start in the SmartWare application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. 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 DFQ file with the SmartWare program.
Step 3. Update SmartWare to the latest version
The fault may also lie with the SmartWare program, it is possible that SmartWare Query Definition requires a newer version of the program. This can be done using the application (if it provides such options) or from the SmartWare Corporation website and install the latest version.
Step 4. Check for the following problems with the DFQ file
If the above steps do not help, you can assume that the file itself is not correct. 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 DFQ file. The only repair option is to download the file again.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file DFQ or the program directory. However, remember that not every infected DFQ file can be recovered, so it is important to take care of regular backups.
A typical compatibility error - the program does not support the older version of the DFQ file. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or 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 DFQ file corruption. You can restore the file from a backup or use SmartWare Corporation help.
The program indicates that the file is encrypted or corrupted. The encrypted file DFQ 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. These directories are write-protected to them and it's very hard to fix this problem. Copying the DFQ file to another location will fix the problem.
This problem only occurs with more complex files. In this case, the DFQ file is blocked by the first application to open it. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file DFQ to close. Some anti-virus or backup software may occupy the DFQ file for a certain period of time. If the problem persists, restart the machine.
