The synchronize action will make two folders mirror each other, keeping the
latest changes made to the files in either folder. New and updated
files are copied both ways. Renames and deletes on either side are repeated on
the other.
For example, you have two computers. You keep a copy of pictures, documents,
and/or tunes on both. Changes often occur on both computers. You want SyncToy
to notice additions, deletions, changes, and renames on both computers, and
then do the right thing to bring the folders back in sync. Synchronize is
the SyncToy action to use.
Every file in the left folder that is new or changed is copied to the right
folder.
Every file in the left folder that has been renamed is renamed in the right
folder.
Every file that was deleted from the left folder is deleted in the right
folder.
SyncToy does not actually delete any files. It merely moves the files to
the Recycle Bin.
The process is repeated for files in the right folder.
SyncToy does not delete folders.
If both sides were renamed since the snapshot, the name from the left side will be used. If a snapshot does not exist, the name from the left side will be used. If only one side got renamed since snapshot time, the other side gets renamed to match.
