什么是 FW 文件？
An FW file contains information used to update a device's firmware. Many types of devices, including digital cameras and portable media players, use updates saved as FW files. Typically, users install an FW file on a device by transferring the file to the device's memory card or connecting the device to their PC via a USB port.
更多信息
Firmware controls how a hardware device communicates with other hardware devices. Periodically, hardware manufacturers may release firmware updates, which fix firmware bugs or allow a device to communicate with additional (often newer) types of devices.
Sometimes, manufacturers provide firmware updates to users in the form of FW files. After receiving an FW file, users are meant to install it on an appropriate device.
如何打开 FW 文件
Most FW files are not meant to be manually opened. To install an FW file on a device, refer to that device's user manual or the instructions included with the file.
If you are an advanced user who wants to analyze the data an FW file contains, you can do so using Binwalk (multiplatform).
