I have been using BTcloud for many years to sync between laptop and desktop. On the Desktop BTcloud points to C:\Users\username\BT Cloud. This location is redirected to a large storage on disc 😧 with lots of space, but now, when it runs it fails with a message "You've run out of space on the local disc c: and we cannot continue". How do I fix this? It worked fine in the past. Disc C: has 81 GB free space. I have made major changes to reduce the amount of data to sync.
