How to open K9 file?

The main problem with DataFlex Index is that the K9 file is incorrectly associated with programs. This causes the file K9 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 K9 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 DataFlex

The first step is to check if the computer has the DataFlex program installed. To do this, enter the name DataFlex 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 K9 with DataFlex. Below is a list of programs that support the file K9.

Programs to open K9 file

Remember to download programs supporting K9 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of DataFlex with K9 files

If, despite the installed application, the K9 file does not start in the DataFlex application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can select the desired program. 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 K9 file with the DataFlex program.

Step 3. Update DataFlex to the latest version

If, however, after binding DataFlex with DataFlex Index there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the The Database Managers, Inc. page and install.

Step 4. Check for the following problems with the K9 file

Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the K9 file. 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. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our K9 file. However, remember that not every infected K9 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 K9 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.
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 K9 file corruption. The easiest way to restore the file is from a backup or by contacting The Database Managers, Inc., but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted K9 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 operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. It is best to move K9 to a different directory.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file K9 to close. Some anti-virus or backup software may occupy the K9 file for a certain period of time. If this does not work either, restart the device.
