Windows 11 show file extensions

On Windows 11, File Explorer hides the extensions for known file types for some reason by default, but you have multiple ways to make them visible, and in this guide, you will learn how.

A file extension is the three or four letters that come after the period at the end of the name, indicating the file format type. For example, my-notes.txt, my-document.docx, etc. Although extensions are not necessary after saving the file, it’s another visual queue to identify the file’s format quickly. Also, it makes it easier to change compatible extensions as necessary, such as from .txt to .bat when you are writing a script or batch file.
