What is an OFW file

OFW files mostly belong to Update Utility. Primary usage: OFW files are mainly used as firmware update packages for devices.
Some of these files are compressed with a ZIP container, meaning they hold the firmware in an archive form.
In other cases, OFW files are used on e-bikes where companies like OLI Move Plus and Olympia provide firmware updates to refresh device programming.
Additional use: A variant of the OFW file serves as an OrigaLys data file. This file type holds experimental electrochemical data and is managed with specialized software from OriginLab Origin.
Key details summarized by FilExt.com:

If the file is a firmware update package, it must be processed with the official update utility provided by the device manufacturer.

If it is a data file, it should be opened with the appropriate analysis tool, such as OriginLab Origin, available at OriginLab Origin.

FilExt.com note: Some users can rename a firmware OFW file to a .ZIP extension to inspect its contents (if not encrypted), but caution is needed to avoid accidental modifications.
