I have a folder containing a bunch of jpeg files and currently all of the filename extensions (.jpg) are hidden. How can I unhide all the extensions in this folder?
When I do a "Get Info" on any individual file, I can see that the "Hide extension" checkbox is checked but it's grayed out (i.e. disabled) so I can't change it. I've gone to Finder's Advanced Preferences and checked "Show all filename extensions" but that hasn't made a difference. Also, I do have read and write privileges on the files. How do I do this?
