So I noticed that the TWRP NANDroid images have .win extension. I expected .img. Does anyone know if they are using a proprietary format? Or if I can just rename it to .img?
I suppose I'll be brave and rename it and try to flash it via fastboot and see what happens
And regarding Windows hiding file extensions, they've been making that the default setting since Windows 95. So I have to assume that it's the best decision for most users of windows.
Personally, I think it's rediculous to hide the extension. It's one of the first things I change in a fresh install of Windows, followed by showing all hidden files.
