compare folders A & B put diffs in C

Can someone point me to how to
compare folder A with folder B
then put different files in folder C
?
Working on a back-up system.

Thanks!

Hello,

For your scenario, you only want differences placed within C? And the default criteria of timestamp/size is sufficient, correct? And do you need different files from the left *and* the right, and if they are an aligned difference, do you want the newer file or older file? The below script makes several assumptions:

log verbose "c:\bclogs\bclog%date%.txt"
load "c:\folderA" "c:\folderB"
expand all
select left.orphan.files left.newer.files right.orphan.files right.newer.files
copyto all path:relative "c:\folderC"

Please note that Script does not offer a preview before actions are taken, and there is no Undo command supported by BC4. Please test with test folders first while learning how our script syntax works to prevent accidentally altering any important data that a small syntax error could cause.
