Use the steps below to display file extensions in Windows 10.
- Click the folder icon in the taskbar.
Alternatively you could open any other folder on your computer.
- Select the “View” tab at the top of the window.
It is above the folder path field.
- Click the “Show/Hide” button.
It’s at the right end of the ribbon.
- Check the box to the left of “File name extensions.”
The files in the current folder should switch immediately to display their file extensions.
The steps above were performed on a laptop computer using Windows 10, but will also work on any other Windows 10 laptop or desktop computer. You can also show file name extensions in other versions of Microsoft Windows, like Windows 7, Windows 8, or Windows Vista, but the method is slightly different in some of those operating systems.
For example, to show file extensions in Windows 7 you would click the Organize tab in a folder, then Folder and search options, then the View tab and check the box next to Show file extensions.
Note that showing file extensions in Windows 10 makes it much easier to change those file extensions. While that might be desirable for some users, others may find that they accidentally change those file extensions, which can corrupt files.
If you only needed to show those extensions temporarily, then it’s a good idea to hide extensions when you’re done. You can hide file extensions the same way you displayed them. Double-click a folder to open File Explorer, select the View tab, then clear the check box next to “File name extensions” on the Show/Hide menu.
There are some additional File Explorer options in that ribbon that you might want to adjust. For example, you can adjust more folder options by selecting “Options” on the “View” tab, then clicking the “Change folder and search options” button. This menu shows additional personalization options to help you control you r file and folder display.
