Extension not shown

[PinkiPad]

There is an instance when a file's extension doesn't show. I know there is a simple fix but can't remember it or find it.

Here is one example:

Start/computer/c:/websites/name

On the right is a list of files
comments
pages
zerp

What I want to see is
comments.php
pages.html
zerp.exe

How do I unhide the hidden extensions?

Open Folder Options, unselect Hide extensions for known file types.
