The file does not open. I do not know what format it is, what should I do?

File extensions are hidden by the Operating System. To see the extensions of all the files, including the file, which we cannot open, follow the steps listed below:

  • Enter Windows Explorer or click My Computer
  • Go to the Control Panel and then to Folder Options
  • Select the View
  • Find the setting specified as Hide extensions for known file types , then Clear this field.
  • Click OK
But remember that you cannot use this method for files with extensions .exe, .com and .bat
