How to extract .win file content?

I have a 2D game I was playing, and would very much like to extract its sprites.
The game resources are most likely in a file name data.win
Is there any method to extract those sprites and images from that data.win file?

Yes, and 7zip also can’t seem to open it.
I tried Ivan Image converter which allegedly can open .win image, but i guess this data.win is comprised of more than the game sprites/images. Musics and sound effects must be in there too.
