How to open QDC file?
The main problem with Quick Devis Database is that the QDC file is incorrectly associated with programs. This is manifested by the fact that QDC 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 QDC 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 Quick-Devis
An often overlooked issue is to make sure that Quick-Devis is installed on the computer. The easiest method is to use the system search engine by entering the program name Quick-Devis in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file QDC with Quick-Devis.

Programs to open QDC file
Remember to download programs supporting QDC files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Quick-Devis with QDC files
If, despite the installed application, the QDC file does not start in the Quick-Devis 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 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. Checking the "Always use the selected program ..." box will permanently associate the QDC file with the Quick-Devis program.
Step 3. Update Quick-Devis to the latest version
If, however, after binding Quick-Devis with Quick Devis Database there were still problems, you should update the program to the latest version. In this case, use the Quotalys Ltd. website or update the program from the application.
Step 4. Check for the following problems with the QDC file
If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:
The QDC file may be unusually small compared to the original file. Usually this applies to QDC files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the QDC file that we want to open. However, remember that not every infected QDC file can be recovered, so it is important to take care of regular backups.
Older version of QDC file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged QDC files. The easiest way to restore the file is from a backup or by contacting Quotalys Ltd., 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 QDC files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. If possible, you can try to move the QDC file to another location.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Closing other programs should help. If the error persists after closing other programs, wait for a while. However, some background programs may block the QDC file while scanning. If the problem persists, restart the machine.
