Hi,
With sync toy you can sync data between your fixed Disks and USB ones or even Mapped Network Drive.
Sync Toy does not care about the Disks but folders. it Sync data based on the folders.
So you can create a folder pair with the action(synchronize/echo...) that you perfer.
But be aware that, when sync data with sync toy, do not make any modifications under the folder.
Thanks,
Baoke
