What is an FW file?
An .FW file is a firmware update file. Hardware manufacturers use these files to update the internal software on physical devices. Devices that use .FW files include fitness trackers like the Xiaomi Mi Band, satellite receivers, media players, cameras, and surveying instruments. Sometimes, the .FW extension is used for completely different purposes. For example, KOMPAS-3D CAD software uses .FW files to store 3D design fragments.
How to open FW files?
Usually, you do not open an .FW file directly on your computer. Instead, you transfer the file to a hardware device using a specific software application. For example, open-source software like Gadgetbridge installs .FW updates on smartwatches. Some .FW files are actually standard GZIP or ZIP archives containing multiple system files. You can extract these compressed .FW files using standard archive tools like 7-Zip or WinZip.
