Detailed explanation-1: -Changing a file’s extension can “force” the file to open in a different program. This can be useful when a file will not open using the default program. However, a better way to change what program opens a certain file is to modify the file’s properties.
Detailed explanation-2: -The operation of changing the file extension on Windows should have no effect on the file itself. However, if you opened the file when it was a . txt (so it opened in Notepad ), and then saved it-you may have corrupted the file.
Detailed explanation-3: -Changing the extension doesn’t change what the file ultimately is. An MP3 isn’t a Word document, so changing the file type from MP3 to DOCX won’t suddenly make Word a music player. However, if the file types are similar (for instance, JPG and PNG), then the software may still be able to open the file.
Detailed explanation-4: -Extensions tell your computer which application created or can open the file and which icon to use for the file. For example, the docx extension tells your computer that Microsoft Word can open the file and to display a Word icon when you view it in File Explorer.
