Open FW File
FW extension file contains useful firmware update information for a hardware device, specifically video or photography.
The FW file can be used for digital cameras, camcorders or portable players (Hardware), and can be transferred via a memory card or direct USB connection.
Each hardware manufacturer has a different method for updating a device, so to do so using a FW file, you must follow the instructions in the device's user manual or included with the file.
FW files are update files, therefore opening them manually is not recommended, in fact, there is no specific software to open and work with a FW file.
