I'm trying to run this code:

Set a = "c:\a"
set b = "c:\b"
xcopy /d /y %a  %b

But I don't know why it cannot recognize the second path.

The export in cmd is like xcopy /d /y c:\a

Does anyone know why?

You should not have spaces before and after the "=" sign when setting the variables. And as Ignacio said, variables should end and start with %

So this should work correctly:

set a="c:\a"
set b="c:\b"
xcopy /d /y %a% %b%

Batch variables begin and end with a %.

xcopy /d /y %a% %b%
