Notes about the KMDR file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The KMDR file type is primarily associated with 'Kommander' by KDE Web Dev Team. Kommander is a two part application. The first part is the editor where you visually build dialogs and applications and edit the scripted elements. The second part is the executor which processes the generated XML file. Kommander is a non traditional "disruptive" technology. It does not compile applications, but it does not rely on interpreted scripting to build it's interface. It relies wherever possible on compiled functions. It produces non-compliled dialogs and applications at a very small file size that run fast and can be distributed without binary compatibility issues.
