Make filename extensions hidden in specific folder (Desktop) or file (.jar) I want to make all filename extensions visible (which I did in Finder -&gt; Preferences -&gt; Show All Filename Extensions = true) except the ones in a specific folder (Desktop), or a specific .jar file.
Now, I can just hide all extensions and then just unhide the .jar file but I am afraid it will take too long if I can't select all the documents and Get Info but as far as I know, it will bring multiple Get Info windows as they do not have things in common?
What can I do?
I do not have Xcode installed by the way.

You can write an AppleScript that uses Finder’s extension hidden property to do this. See the accepted answer here:
