Have you encountered a problem with a MNO file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a MNO file here. In the further part of this page we have added a list of programs that should open your MNO file. It is enough you choose a proper application for your operating system, download and install it.


The file extension MNO is used for so-called Design Notes (still stands for Macromedia) of the web page editor Adobe Dreamweaver. Usually, the ending MNO is used as a double ending, that is attached to an existing extension, for example bild.Jpg.Mno.

These files contain additional information about the associated file, such as comments, the status of the file, and the link to the original file. In addition, Dreamweaver uses Design Notes for integration with Adobe FireWorks and Flash, so when you edit an image file, it automatically opens the right program and the changes you make will immediately affect the page.

If you do not want to use the Design Notes, you can disable this feature in the properties of the site, 'Site-> Manage Sites-> Edit' under the 'Advanced' tab and the 'Design Notes' category.

How to open a MNO file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the MNO file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a MNO file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support MNO files. At this point we are looking for disk space where the application was installed in and we can link it with a MNO file. Since then, our operating system will use the selected program to support all MNO files.

Other issues

Despite the described problem with MNO there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the MNO file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the MNO file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
