Record marked as obsolete and not updated for a long time.
The vzn file extension identifies proprietary encrypted bitmap files associated with WinVZN. The format was used to store picture images for viewing in that software.
WinVZN was developed by inData Corporation for Windows. The format is obsolete: the original viewer is no longer available or supported by its developer.
The original WinVZN viewer is no longer available or supported by its developer. Opening a vzn file may therefore require recovering the original software or using a compatible legacy system.
Because vzn files are encrypted and the original viewer is no longer available, conversion requires software that can decrypt and render the image, such as the original WinVZN viewer. Without compatible software, the file cannot generally be converted to a common image format.
