Problem

Most files on Windows PCs have a File Name followed by a period followed by a "file extension" of three or more characters.

By default, Windows hides the dot + file extension from you.

This was a spectacularly bad decision by Microsoft.

The file extension is what Windows uses to decide what application owns each of your flies, what to do when you double-click an icon and so forth.

To make it worse, Windows also hides some files and folders from you altogether.

Sooner or later, you'll need to view or change a file extension or search for files of a certain extension, but as long as Windows is hiding your files from you, you can't do that.

Worse: If you need to find files of a certain extension, Windows Explorer's File Search feature won't find them if Windows is hiding extensions. That is, if you search for *.TXT, it won't find your .TXT files.

And Worse: Some programs, notably Office ones, won't even show extensions in file save/open dialog boxes. This can really turn round and bite you. Suppose you've learned that saving a file as a .PPS is the same as saving it as a PowerPoint Show. So you choose File, Save As, and add a .PPS extension to the file name in the Save dialog.

You think you've just saved MyShow.PPS

Wrong. PowerPoint has tacked on its usual .PPT extension but since Windows is hiding file extensions from you, you don't see it. You've actually just saved MyShow.PPS.PPT ... which of course behaves like a regular PowerPoint file, not a Show.

To avoid confusion, teach Windows to show you your stuff. Here's how:

Solution

• Double-click My Computer
• Choose Tools, Folder Options from the menu bar of the "My Computer" window
• Click the View tab
• Scroll down a bit and remove the check mark next to "Hide extensions for known file types" as shown below.
• Under "HIdden files and folders" click "Show hidden files and folders"
• Make sure the other options are set the way you want them for all folders on you computer
• Click OK
