When trying to copy big files (total size > 50G, size of each file around 2-3.5G) to external USB stick formatted with exFAT, it will always failed.
After the copy process started, the copying job can be seen with state “Waiting” in Activity of the app. Several minutes later, it will pop up a message box - “Invalid operation: A file already exists at this location, or an invalid operation was attempted.” And the state of this job is changed to “Failed”.
It happened always. I’ve tried several USB sticks.
Device is Wireless Pro 3TB.
