1. Upload some file to ext-release-local.
2. Delete the file by right clicking it and choose Delete.
3. Go to the Trash Can and restore the file (note you need to restore the file specifically and not from the root.
4. Even though the restore works, you will see this error in the log:
2016-09-12 10:28:35,095 [http-nio-8082-exec-2] [ERROR] (o.a.r.s.f.FlatMoveCopyServiceImpl:180) - About to delete auto-trashcan:ext-release-local/nservicebus.nhibernate.3.0.0.nupkg but folder doesn't exist
As mentioned, if you restore the file from the root (right click on ext-release-local - restore) this error doesn't show
