Windows cannot open this file:

example.diff

To open this file, Windows needs to know what program you want to use to open it...

🔴 Can I change the extension of files?

Changing the filename extension of a file is not a good idea. When you change a file's extension, you change the way programs on your computer read the file. The problem is, changing the file extension does not change the file format.
