Each Design Notes file stores information for a single document. If one or more documents in a directory has a Design Notes file associated with it, Dreamweaver creates a _notes subfolder in that directory in which to store Design Notes files. The _notes folder and the Design Notes files it contains are not visible in the Site window, but they show up in the Finder or in Windows Explorer. A Design Notes file name is made up of the main file name plus the extension .mno. For example, the Design Notes file associated with avocado8.gif is avocado8.gif.mno.
Design Notes files are XML files that store information in a series of key/value pairs. The key describes the type of information that is being stored, and the value represents the information itself. Keys are limited to 64 characters.
The Design Notes file for foghorn.gif might look like this:
<?xml version="1.0" encoding="iso-8859-1" ?><info> <infoitem key="FW_source" value="file:///C|sites/dreamcentral/images/sourceFiles/foghorn.png" /> <infoitem key="Author" value="Heidi B." /> <infoitem key="Status" value="Final draft, approved by Jay L." /></info>
