How to open COM file? 9 steps

If the user comes across a file named DOS Command Format, but is unable to open it, the first thing to do is to take the following steps:

  1. Check if the DOS Command Format file can be handled by the given operating system. Files with the COM extension may not be supported by the operating system you are using.
  2. Check if the FixExec or Microsoft Windows, Parallels Desktop program is installed in the system. The solution to this problem is to install the appropriate software that supports files with the extension COM.
  3. Verify that the default application for handling COM files is one of the following software tools: FixExec, Microsoft Windows, Parallels Desktop. If this is not the case, the COM files should be associated with the appropriate application by displaying the properties of the DOS Command Format file and in the "File type" section, press the "Change" button. On the list, search for one of the FixExec, Microsoft Windows, Parallels Desktop applications and confirm.
  4. Software programs that open COM file extension

  5. If the DOS Command Format file has been downloaded from the Internet or copied from another medium, it may be corrupt. In this case, the FixExec, Microsoft Windows, Parallels Desktop programs will not be able to open the DOS Command Format file despite their presence in the system. Re-downloading or copying the file may fix the problem.
  6. The antivirus program can identify the virus with which the DOS Command Format file has been infected and at the same time blocks the opening of the file. The best solution in this case is to run a virus scanner and check the system for viruses.
  7. The DOS Command Format file may be saved in a way that is no longer supported. Sometimes it happens that despite the COM extension, such files contain data saved in a way that prevents them from being opened by FixExec or Microsoft Windows, Parallels Desktop.
  8. The condition for the correct handling of the DOS Command Format file may be the regular download and installation of the application update in which the user wants to open it. Determine the version of your program and, if necessary, install the latest one.
  9. Sometimes the user unknowingly tries to open a file with a shortcut that points to a place where the file is no longer there (it may have been previously deleted).
