Often it's much quicker to do XCOPY
d:\*.xyt h: /s /v /d:MM-DD-YYYY
You don't need the MM-DD-YYYY if you just want to copy newer files. And I
use Xcopy32, to preserve long filenames (not necessary for Xy files of
course).
I have a DOS batch file for copying from my desktop to my laptop to prepare
it for travel (and another DOS batch file to copy the other way when I get
home). It has lines like these (where my laptop is on the LAN mapped to "l"):
xcopy32 c:\xy\*.* /c /e /f /v /d l:\xy\
