How can I change the Windows 10 file system's display from kibi/mebi/gibi to kilo/mega/giga? [duplicate]

Further research shows this is not possible natively in Windows.

This cannot be changed. Windows Explorer will display the size column in the smallest unit, “KB” for simplicity. If you select your file and view the details pane, you will see the file in its true form, whether it’s MB or GB. There are third party programs that are able to do what you are asking, but unfortunately, I do not think it would come for free.

THIRD PARTY DISCLAIMER

Using Third Party Software, including hardware drivers can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the use of Third Party Software can be solved. Using Third Party Software is at your own risk.

There are some third party dir and explorer utilties you could try, such as TakeCommand and TotalCommander, which may provide such functionality.
