Why does “Copy” replace stuff instead of merging it?
In Windows, if I overwrite a folder
def/doc, (1) files existing in
abc/doc but not in
def/doc are simply added to
def/doc; (2) files existing in
def/doc but not in
abc/doc do not change; and (3) files existing in both folders are replaced. But in Mac, all files in
def/doc are deleted and files in
abc/doc are copied. I am not talking about which should be the more correct behavior, but was wondering if Mac can be tuned to how Windows behave, because I am more comfortable with such behavior.
I found that Lion now behaves just like Windows, but in Snow Leopard or older version, how can I make Mac OS behave like what I described?
