Have you encountered a problem with a MNU 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 MNU file here. In the further part of this page we have added a list of programs that should open your MNU file. It is enough you choose a proper application for your operating system, download and install it.


MNU files are customization files for the Adobe Photoshop image-editing software. In it, data for own Menkonfigurationen be stored, such as which Meneintrge to be displayed at all, or whether a menu should be highlighted.

For example, a new CS5.Mnu is included with Photoshop CS 5, which highlights all new menu options. There are also presets like 'Film and Video' or 'Image Analysis'. To use a MNU file, you can usually simply double-click it or reach it under 'Window-> Workspace. If a menu setting should appear here, the MNU file must be copied to 'Preferences / Customize' in the Photoshop main directory.

You can create or change your own menus under 'Edit-> Mens-> Tabs (Men)'. There is no way to load an MNU file. For a menu adjustment to be selected here, the corresponding MNU file must be in the correct directory (see above).

Especially useful are MNU files to save your own customization (for example, for a new installation) or to transfer them to another (work) computer.

How to open a MNU file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the MNU 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 MNU 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 MNU files. At this point we are looking for disk space where the application was installed in and we can link it with a MNU file. Since then, our operating system will use the selected program to support all MNU files.

Other issues

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

- verify that the MNU 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 MNU 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.
