Markzware ( has released MarkzTools for InDesign, an InDesign plug-in that allows users to open a higher version of an InDesign document in a lower version.

For instance, an InDesign CS6 user of MarkzTools for InDesign can open an InDesign CC (Creative Cloud) or CC 2014 document. MarkzTools for InDesign takes the guesswork out of working with Adobe InDesign documents created in varying versions and releases. This includes InDesign CS5, CS5.5, CS6, CC, and CC 2014.
MarkzTools for InDesign requires Mac OS X 10.6.8 or higher and one of these Adobe InDesign host applications: Adobe InDesign CS6 Mac, Adobe InDesign CS5.5 Mac, or Adobe InDesign CS5 Mac. A Subscription Bundle is immediately available and entitles users to use MarkzTools for InDesign for a full year from the purchase date. Prior to the end of the year’s subscription, Markzware’s Loyalty Program will prompt users to renew their subscriptions at a discounted rate.
