Mac OS X user wanting to upgrade to latest Acrobat Pro from Acrobat Pro 9. I have thousands of files in the "Organizer" that is no longer supported. I can manually add a tag to each file and replace the original now with a searchable tag; however, this process could take weeks. I want to keep the original name of the file, but add a tag (the tag would be the current category name) that I can now find all the files since there is no longer an Organizer. I would like to just highlight all my files in a particular Organizer category and apply the same tag to each one simultaneously while keeping the name of the file.
