What is CQS file?
The CQS file has been categorized as Misc Files. Additionally, the Misc Files category contains 6033 of other files. ConQuest Search Data Format is supported by 1 operating systems. The file will work on Windows systems, unfortunately not on others. It is recommended to use ConQuest to handle this file. This is a program created by Cambridge Crystallographic Data Centre.
How to open CQS file?
An often recurring problem with ConQuest Search Data Format is that CQS is not associated with the correct program file. Thus, when you open CQS, the program selection wizard or some other program starts. This problem can be easily remedied.
The first thing you should do is just "doubleclick" on the CQS 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 ConQuest
The first step is to check if the computer has the ConQuest program installed. The easiest method is to use the system search engine by entering the program name ConQuest 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 CQS files.
Programs to open CQS file
Remember to download programs supporting CQS files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of ConQuest with CQS files
If the application is or has been freshly installed, but the CQS file still does not use the ConQuest program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting 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. The "always use the selected program ..." field will set the ConQuest application as the default for handling the CQS file.
Step 3. Update ConQuest to the latest version
If, however, after binding ConQuest with ConQuest Search Data Format there were still problems, you should update the program to the latest version. In this case, use the Cambridge Crystallographic Data Centre website or update the program from the application.
Step 4. Check for the following problems with the CQS 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 CQS file. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our CQS file. However, remember that not every infected CQS file can be recovered, so it is important to take care of regular backups.
Older version of CQS file may not always be supported by the latest software version. 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.
There can be many reasons for the failure. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular CQS file corruption. You can restore the file from a backup or use help.
The program can also signal the fact of encryption. The encrypted CQS 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. The problem is only writing to the file, not reading it. If possible, you can try to move the CQS file to another location.
This problem only occurs with more complex files. In this case, the CQS 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.
