I guess we can get skwire to move the thread to Finished then 

Done.  Really slick batch file work, too, 4wd.

What am I missing?

choice  

MS in their infinite wisdom included the choice.com/choice.exe DOS command in all versions of Windows from 3.1 and DOS 6.x onwards except 2000 and XP.

You can grab the choice.com command from a set of DOS 6+ disks - I've attached it below for Windows x86 only.

Also, I'm sorry to say, v9 SHA-1 calculation doesn't work due to the lack of Delayed Expansion, (enabling limits using ! in filenames), so I'm writing a small hash program so I won't have to use fciv.exe which is why I have to use the for loop to get the value I want.
Why they couldn't just output the hash value without any fluff is beyond me.  

So, I should have another v9 up with a separate hash program later today.

Done.  Really slick batch file work, too, 4wd.

Spoke too soon there - give me a couple of hours though  

OK, back with v9.5:

• No longer requires choice.com, so it should work OK on W2k and XP.
• Now has a dedicated hash program so the SHA-1 comparison works properly, (put it in the same folder as the batch file).
• Checks to see if the Source and Destination are the same, it'll exit if they are.
