location of custom PDF job options file
Apparently Adobe changed the location where custom PDF job options files are stored. Some years ago, under Mac OS, the files used to be in /Library/Application Support/Adobe/Adobe PDF/Settings, the issue is when we drop a custom job options file in this folder, InDesign and Illustrator will not read the file. Instead we we need to store the custom job options file to the new location /Users/zaidalhilali/Library/Application Support/Adobe/Adobe PDF.
I understood from a client that same changes were made to the location of custom PDF options files under Windows platform too.
Did Adobe announce these changes? Or, are the paths to the new storing location mentioned anywhere on Adobe site or perhaps on the "Adobe PDF Creation Settings"? I'm sure Offset printers, pre-press guys and designers do look for this information.
