CMA File Extension

How to open CMA file?

After double-clicking on the unknown file icon, the system should open it in the default software that supports it. If this does not happen, download and install the Cognos TM1 software and then manually associate the file with it.

Step 1. Download and install Cognos TM1

If there is no Cognos TM1 or similar software in the system that supports files with the CMA extension, you must first download and install it. Below you will find a list of the most-used applications that work with CMA. After going to the subpage of the program you will find a link to the developer's website, where you can safely download the software installer.

Step 2. Associate Cognos TM1 with the CMA file extension

If the user already has one of the applications installed, the next step will be to associate it with the file extension CMA. This can be done in two ways - one is to manually edit the Windows Registry and HKEY_CLASSES_ROOT keys. The second way is simpler and definitely recommended for less advanced users.

• Right click on the unknown CMA file you want to open
• Select "Open with" from the menu
• Click "Choose another application"
• Click "More applications"
• Click "Find more applications on this PC" and indicate the installation location of the appropriate program
• Finally, select the "Always use the selected program to open CMA files" option and confirm the whole operation.

Remember! Manually editing the system registry is only recommended for advanced users, and changes made to it without proper knowledge may result in damage to the system.

Step 3. Check out other possible problems related to CMA files.

Sometimes it happens that despite having the right application and the correct configuration, there are still problems with opening the CMA files. You should then find out what is the reason of the problem.

• Check if the CMA file is not infected - When the file CMA is infected with a virus or malware, it probably will not be able to be opened correctly. In this case, scan the CMA file and take the actions recommended by the antivirus program installed on the system. Most often it is disinfection or deletion of an infected file.
• Check if you, as the operating system user, have appropriate permissions to work with the file CMA
• Check if the icon is an element of the correct file but not only a shortcut to the location where the CMA file no longer exists.
• Check that the system has the necessary resources to run the Cognos TM1 application and open the CMA file.
• Check if the file is complete - Sometimes it happens that the CMA file was not copied completely from the external Flash memory, or downloaded from the Internet. When the file is incomplete, it is not possible to open it correctly. In this case, please download or copy the file CMA again.

Step 4. Contact an IT expert

When all of the above methods have failed, it remains to contact an IT specialist or developers of the COGNOS TM1 program.
