Reader Greg Geitzenauer is getting the tiniest bit tired of selecting individual files in order to hide their extensions. Here’s his story:

To show the file extension for a particular file’s name, one only needs to choose “Get info” from the File menu and uncheck the “Hide extension” box. Is there a way to do the same thing for a selected group of files all at once?

Indeed there is. The trick is that the files must be in the same folder. Once they are, simply Command-click on the files you’d like to alter and press Command-I. Unbeknownst to many, when you perform this action, up pops the Multiple Item Info box. Here you’ll find the Hide Extension option under the Name & Extension triangle. Just enable this option and the file extensions will vanish from each selected file’s name.

Note that the Hide Extension option won’t work if you’ve included a folder in your selections.
