Step 1: Open File Explorer
Start by opening File Explorer. This can be done by clicking the folder icon on your taskbar or searching for “File Explorer” in the Start menu.

By checking this box, you’re telling Windows, “Hey, show me the details!” This will reveal the extensions for all file types.
After completing these steps, you’ll notice that each file will now show its extension, like .txt for text files or .jpg for images. This added information helps you identify file types at a glance.
