Copy/Replace files only if newer or different
Here is an exciting thing you can do with Copywhiz.
You can copy only newer or modified files by skipping identical files. This feature will make the copy process much quicker.
It is useful if you are backing up your files to the same destination. Only new & changed files are copied.
Also, to ensure that the destination file does not get replaced with an older version of the file, you can
skip files that are
identical/newer in the destination folder.
Eg. When maintaining a set of music files on yet another drive (USB pen drive, music player, etc), you can select these options to
update the collection with only newer or updated files saving you several minutes each time.
To detect if the files are identical, Copywhiz compares the file sizes & dates.
