Notes about the WZN 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 WZN file type is primarily associated with 'WhizNotes' by AvniTech Solutions. Older version of what is now WhizFolder and now uses .WZFOLDER for the extension.
