Vista Tweak 3: Turning 'show File Extensions' on

Why this is turned off by default is beyond me but Microsoft must be thinking this is useful to users. It is not! There are still people who actually don’t know how make the file extensions visible and there are people who don’t even know that filenames normally have an extension. Displaying file extensions has the advantage that you know immediately with what file type you are dealing (that is unless the file extension was set wrong). But if you can see an .exe extension on an unknown file it is a lot more helpful than just counting on the file’s icon. To turn on ‘show file extensions’ follow these simple steps:

  1. Go to Start Menu/Control Panel and double click the Folder Options icon
  2. Click the View tab and in the Advanced Settings list uncheck the item called Hide extensions for known file types
  3. Click Ok and you are finished

    Thanks for the tip, an easy find to your blog from a google search. Info was exactly what I needed.
    Regards. PS – note that an array error is showing up near the blog banner.

    Strange, I thought this is what you had to do, but it doesn’t work this machine. Every tmie I try it, nothing changes all extensions are hidden for known file types.

    Anyone know where to find this in the registry, maybe you have to manually set it there

    Thanks for this. I can never remember how to turn on file extensions. Only been using XP/Vista for 8 years now…
