The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:
Very often, the file may be size 0 or incomplete. Usually this applies to QDA files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file QDA or the program directory. As a result of the scan, sometimes it is not possible to recover QDA files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the QDA file. 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 QDA file corruption.
The program can also signal the fact of encryption. The encrypted QDA 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 QDA file to another location.
This problem usually affects more complex files. In this case, the QDA file is blocked by the first application to open it. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. However, some background programs may block the QDA file while scanning. If the problem persists, restart the machine.
