The WZP file extension is associated with firmware update files used by some Chinese GPS navigation devices. The files contain device firmware or update data intended for compatible hardware.
The exact manufacturer and device models that use this format have not been verified. Because the format is device-specific, it should be used only with the update procedure provided for the relevant device.
A .wzp file is not normally opened on a computer. It is applied to the compatible GPS or navigation device using that device's firmware-update process.
Do not install the file unless it is intended for the exact device model, as an incompatible firmware update may prevent the device from working.
Firmware files are not normally intended for conversion. A .wzp file should remain in its original form and be used only with the compatible device's update procedure.

The wzp file extension is associated with the AMP1-16 update service. AMP1-16 was developed by the Wohler.
Update service can send files as an e-mail message and due the reason of the safety sends ZIP files with renamed file extension ZIP to WZP. The WZP file extension can be renamed back to ZIP and after that can be extracted.
