I'm having trouble finding the quad file which I installed using the drag and drop app. The curve shows up in the QTR print dialog as one of the curves in the Curves 1 menu. Curve View works when I drag a .quad file on it. It does not work when I drag the corresponding .txt file on it --- or I don't know how to make it work for a .txt file. The install works but I can't find where QTR puts the installed files so I can use the Curve View app. I searched the mac for ".quad" and didn't find any quad files. I have not been able to find out how to view hidden files on a mac. Is it in a hidden folder? If so, how can if view the folder. How can I locate the .quad files. I'm on a Mac running Yosemite. Thanks John
