How to open CK9 file?

The first thing you should do is just "doubleclick" on the CK9 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

In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support CK9 files.

Programs to open CK9 file

Remember to download programs supporting CK9 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of with CK9 files

If the application is or has been freshly installed, but the CK9 file still does not use the program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. 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. Checking the "Always use the selected program ..." box will permanently associate the CK9 file with the program.

Step 3. Update to the latest version

If, despite the association of the program with the DVN Cookn Cookbook Backup Format file, the file still does not open, check the program version and possibly update it to the newest version.

Step 4. Check for the following problems with the CK9 file

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. This suggests truncating the CK9 file contents when downloading or copying. 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. However, it is important to scan the entire system, not only the file CK9 or the program directory. As a result of the scan, sometimes it is not possible to recover CK9 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of CK9 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 this. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular CK9 file corruption.
The program can also signal the fact of encryption. The encrypted file CK9 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.
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 CK9 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. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the CK9 file for a certain period of time. If this does not work either, restart the device.
