A filename has a name and an extension separated by a period. The extension helps Windows identify which application can open a file and which icon File Explorer displays. For example, a filename ending in .txt indicates a text-file association.

Changing an extension by renaming a file does not convert its contents to another format. Microsoft cautions that changing the extension changes the filename only; use an appropriate application’s export or conversion feature when you need a different format.
File extensions are not the same as hidden files
The extension setting controls whether File Explorer displays the endings of filenames. It is separate from Hidden items, which controls whether hidden files and folders are shown. To display hidden items, use File Explorer’s separate View > Show > Hidden items control; turning on file name extensions does not reveal hidden files.
