What is a KMDR file?

KMDR files mostly belong to 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.

Unable to Open a .KMDR File? Quick Solutions:

Since .KMDR files can come from different programs, they aren't universally openable.

  1. Identify the Source: Receiving this file from a Linux developer or a KDE scripting workflow strongly suggests it is a Kommander dialog file.
  2. Check the Header: Inspect the first bytes in a text editor or hex viewer:
    • <?xml: Indicates a standard Kommander XML script.
    • PK: Suggests a zipped archive.
    • Unreadable binary: Implies a proprietary format.
  3. Use the Original Software: The original program is usually required to open it properly. Try Kommander (by the KDE Web Dev Team), Kate, or a standard text editor; if uncertain, ask the sender.
  4. Use this Webpage: Drag and drop the file into our viewer to detect the format, extract readable text or metadata, and preview when possible.
