Hi there. I just found the file that WDSync tries and fails to synchronise (in my case “family_tree_builder_8199.exe”). Though, it won’t help to delete this file only on the side of the computer. Don’t forget to also delete this file or parts of it on the MyCloud-side too, otherwise WDSync will start running itself to death again, blocking your LAN or WLAN with this. It tries to synchronise the file back to the PC.
Hope, I could help.
