How to open CM file? 9 steps

The following recommendations and steps will help you open the CLEO Custom Mission file in case you cannot do it in the standard way:

  1. Check if the CLEO Custom Mission file can be handled by the given operating system. Files with the CM extension may not be supported by the operating system you are using.
  2. Check if the CLEO or Grand Theft Auto: San Andreas program is installed in the system. If there is no such program, install it (or download it earlier).
  3. Make sure that one of the CLEO, Grand Theft Auto: San Andreas programs is the default application for opening CM files in the system. If not, open the dialog box with the properties of the CLEO Custom Mission file and use the "Change" button on the "General" tab. Choose one of the CLEO, Grand Theft Auto: San Andreas applications to open the CM files.
  4. Software programs that open CM file extension

  5. Files ripped from external media or downloaded from the Internet may have a damaged structure. In this case, the CLEO, Grand Theft Auto: San Andreas programs will not be able to open the CLEO Custom Mission file despite their presence in the system. Try to download or copy the file again.
  6. The antivirus program can identify the virus with which the CLEO Custom Mission file has been infected and at the same time blocks the opening of the file. In this situation, it is recommended to scan all data media in the system for viruses.
  7. The CLEO Custom Mission file may be saved in a way that is no longer supported. Sometimes it happens that despite the CM extension, such files contain data saved in a way that prevents them from being opened by CLEO or Grand Theft Auto: San Andreas.
  8. The condition for the correct handling of the CLEO Custom Mission file may be the regular download and installation of the application update in which the user wants to open it. Check the app for up-to-date information and, if necessary, install the latest version.
  9. In some cases, the user initiates the opening of the file with a shortcut that leads to a location where it is not present.
  10. The reason that prevents the opening of a given file may be administrative restrictions defined to protect the system by its administrator.
