About the Design Notes API
Adobe® Dreamweaver®, Adobe® Fireworks®, and Adobe® Flash® give web designers and developers a way to store and retrieve extra information about documents. The information is stored in files that are called Design Notes. It gives extra information about documents like review comments, change notes, or the source file for a GIF or JPEG.
For more information about using the Design Notes feature from within Dreamweaver, see Using Dreamweaver.
