I'm using Windows - where does combinator.exe write out to?
So if I use combinator.exe to combine File1 and File2 wordlists ... can I get it to write to a third file?  Because I have no idea where the information is going.  It's appearing by on screen scrolling rather fast, but there's no realistic way to copy it from a fake, Windows-based DOS window (especially since it only displays the most recent 500 or so lines).
The canonical way to do this is simply pipe the output of combinator to hashcat itself, so you don't have to store the result anywhere.

combinator list1 list2 | hashcat ...
Use "combinator list1 list2 > wordlist.txt" to write to a file. works on windows, too.
