Show Extensions for Known File Types in Windows 8

In every version of windows over the last 10 years, Microsoft has kept the visibility of file extensions for known types hidden. Why? To protect the average user from accidentally renaming a file to an unusable file type. Here’s how you configure Windows 8 to show files extensions.

In every version of windows over the last 10 years including Windows 7, Microsoft has a habit of hiding file extensions in order to prevent the average user from accidentally renaming a file to an unknown file type. Windows 8 is no exception to this rule, so if you want to easily edit a file’s extension, you’ll have to change a setting to make it visible.

In desktop mode open up Windows Explorer.

windows 8 explorer

Select the View tab from the Explorer ribbon and select Options >> Change folder and search options.

In the Folder Options window click the View tab and then uncheck the box labeled “Hide extensions for known file types.”

Tip: While you’re here, you might also want to change the Hidden files and folders bullet to “Show hidden files, folders, and drives.”
