Secure Copy 5.x and up - Copy only changed source files to target

When copying only changed files, Secure Copy compares the modified date and size of the file on the source to the same file at the destination.  If the source file has a more recent modified date or different size, the file is copied.

Changing permissions on a file or folder doesn't change the modified date but it does change the “last accessed” date. Consequently, Secure Copy will not (by default) re-copy files that that have not been modified but whose permissions have been altered.
