How to recognize the file format?

Each file name is complemented with a special file extension, the task of which is to inform the user and the operating system about the format in which the data contained in it are saved. To open the file, use a program that supports the format specified by the extension.

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
