As we have shown here in MacMagazineo Finder lets you manage the files stored on your Mac. We’ve also given you several tips for this app — how to restart it and even convert a photo directly there, for example.
Because, in this article, we’ll show you how you can activate an option to make the file name extensions stored there (like .png e .jpg).
See how to do it below!
Open Finder and from the menu bar go to Finder » Settings… (or directly use the shortcut ⌘ command ,). Then click on the “Advanced” tab and enable “Show extensions for all files”.
This will show the extension on all files stored in the Finder.
Bonus: How to show extension only on individual files
If you don’t want file extensions to be shown throughout the Finder, you can do this individually.
To do so, right-click on the file and go to “Get Information”. Optionally, you can also do this using the shortcut ⌘ I or going to Archive » Get Information.
Then click on the arrow next to “Name and Extension” to expand it and check/uncheck “Hide extension”.
Very cool, isn’t it?! ????????
