like to delete files that exist on the destination, but not on the 
source, which is what a /Z or /ZY option does (and of 
course, /CLONE) yet you would like to exclude some of those 
destination orphans from the deletion process.

destination orphans, it takes a second xxcopy step where you reverse

way, a specific exclusion (or exclusion file) will apply towards NOT 
deleting certain orphan files.

Exactly. Also see Garry's solution using source dummies to avoid 
deletion of specific destination objects with /ZY. Both methods will 
work. But both are work arounds that avoid directly addressing 
what "appears" to be a straightforward operation. (But then I'm 
still hung up on xxclone being able to copy registry files, but 
xxcopy not!)

I'm going to go eat the turky.
