Hi Dragan,
>The best NC clone for Windows I ever saw, Windows Commander - see at
http://www.ghisler.com/ - I'm using it for all sorts of stuff, and its install still fits on one floppy. And yes, has a file compare and directory compare, file view (recently added even a mp3 "viewer").
I'm using WC myself now for years and I *really* like it. Great tool!
Well - ok - I have to admit - sometimes I'm using Windows Explorer as well ;-)
