I'm trying to create an Automator service which "receives selected files or folders". If I select a single file in Finder, then go to the Finder:Services menu, my service shows up. If I select two folders in Finder, I also see my service. But if I select only a single folder, the same menu says "No services apply".
Why doesn't the finder services menu recognize that my service is available to be run when only a single folder is selected? How can I run my service?
