What is CNA file?

How to open CNA file?
The most common problem when using Catena Project Format is that a specific CNA is not associated with the program. This is manifested by the fact that CNA files open in unusual applications or do not have an assigned program. How to solve such a problem?
The first thing you should do is just "doubleclick" on the CNA 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 OpEx Catena
An often overlooked issue is to make sure that OpEx Catena is installed on the computer. To do this, enter the name OpEx Catena into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below is a list of programs that support the file CNA.
Programs to open CNA file
Remember to download programs supporting CNA files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of OpEx Catena with CNA files
However, it may happen that the application itself does not cause the CNA file to open in the OpEx Catena application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select 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 select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the CNA file with the OpEx Catena program.
Step 3. Update OpEx Catena to the latest version
If, however, after binding OpEx Catena with Catena Project Format there were still problems, you should update the program to the latest version.
Step 4. Check for the following problems with the CNA file
If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:
Very often, the file may be size 0 or incomplete. This suggests truncating the CNA file contents when downloading or copying. The only repair option is to download the file again.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our CNA file. As a result of the scan, sometimes it is not possible to recover CNA 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 CNA file. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged CNA files.
The program can also signal the fact of encryption. The encrypted file CNA 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.
Some of the system directories are excluded from modification. These directories are write-protected to them and it's very hard to fix this problem. Copying the CNA file to another location will fix the problem.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. 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 this does not work either, restart the device.
