I do have Windows 10 and seems like the version of Snestl 1.2 its not compatible.
I do have a super Ufo and I want to add splited games to diskettes.
Or maybe is there a place where I can get them splitted already?

UCON64 will probably do the trick if nothing else does.

What happens when you use Snestl?  (Are you referring to SNESTool?)

That's because SNESTool is a DOS program.  You would need to use DOSBox to run it under 64-bit versions of Windows.

Don't you think it would be easier to help you if you describe your problems in greater detail?

You will probably want one of the GUI frontends, namely "uf-FOX-1.1-win32-bin.zip".
