Notes about the NZN 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 NZN file type is primarily associated with 'NoteZilla' by Conceptworld Corporation. NoteZilla is a note-taking program for Windows. NoteZilla lets you create virtual sticky notes on your Windows Desktop. The .NZN file represents a single sticky note. Typically, this file is used when sending a single sticky note via E-mail as an attachment to the E-mail message. The file is encrypted, so the XML is not directly accessible.
