What is an MNO file?

MNO files mostly belong to Dreamweaver by Adobe. MNO stands for Macromedia Design Note file. MNO files are data files associated with the Dreamweaver and Contribute applications developed by Adobe.

  • Main Use: Adobe Contribute is a web authorization application that is used to create new web pages or edit existing pages. Adobe Dreamweaver is a web design application that hosts an Integrated Development Environment for the development and designing of websites. MNO files are Design Note files used by Adobe Dreamweaver and Adobe Contribute application to store additional data related to web documents that cannot be integrated into the original file. This information is used by these Adobe programs to receive information about recordsets on a page. The recordset data in an MNO file is stored in an XML format. The MNO file data consists of the main info tag that consists of items with infoitem tag in it.
  • Additional Information: The MNO files take the same file name as that of the file whose description they carry and end up with a double file extension. For instance, the MNO file associated with the home.html HTML file has the filename home.html.mno.
