The CNS file has been categorized as System Files. It was designed by Microsoft. In addition to this file, the System Files category includes 323 related files. Windows 2000 Client Connection Manager Export Format is most often found on 1 operating systems. The file will work on Windows systems, unfortunately not on others. The main program that supports this format is Microsoft Windows 2000. This was created by Microsoft Corporation.

How to open CNS file?

The main problem with Windows 2000 Client Connection Manager Export Format is that the CNS file is incorrectly associated with programs. Thus, when you open CNS, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the CNS 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 Microsoft Windows 2000

The first step is to check if the computer has the Microsoft Windows 2000 program installed. The easiest method is to use the system search engine by entering the program name Microsoft Windows 2000 in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file CNS with Microsoft Windows 2000. Below is a list of programs that support the file CNS.

Programs to open CNS file

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

Step 2. Create association of Microsoft Windows 2000 with CNS files

If, despite the installed application, the CNS file does not start in the Microsoft Windows 2000 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. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. 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 CNS file with the Microsoft Windows 2000 program.

Step 3. Update Microsoft Windows 2000 to the latest version

If, despite the association of the Microsoft Windows 2000 program with the Windows 2000 Client Connection Manager Export Format file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Microsoft Corporation website or update the program from the application.

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

Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:

The CNS file may be unusually small compared to the original file. This is most often caused by a problem while downloading the CNS 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. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the CNS file that we want to open. However, remember that not every infected CNS 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 CNS file. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair CNS file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Microsoft
The program can also signal the fact of encryption. The encrypted file CNS 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 operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the CNS 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. Sometimes it is necessary to wait a while before referencing the CNS file again. Some anti-virus or backup software may occupy the CNS file for a certain period of time. If this does not work either, restart the device.
