Notes about the KNT file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The KNT file type is primarily associated with 'KeyNote' by Marek Jedlinski. Keynote is a flexible, multi-featured tabbed notebook, based on Windows standard RichEdit control. It's always accessible with a single keypress, even if you work in another application. You can have many simple or tree-type notes; mixed freely; all contained within one KeyNote file.
