Replace vs. Merge ...
I am confused about the difference between “replace” and “merge”
in a MacBook Pro. I know that “replace,” completely over-writes the old file or
folder with the new data. However, how is “merge” different? Does “merge” only replace
the specific data that was “changed” in a file or folder, and replaced with
your revisions? Or, does “merge” simply create a second copy of the file or
folder; kind-of performing the same function as Time Machine.
