Your post sounds more like a good Feature Request; the best place for this, is in the Ideas Exchange section. This way someone from WD will be sure to see it and will allow more users to support your idea.
However, I would first search and make sure that there are no other active Feature Requests suggesting the same or similar improvements. If there is, then you could add your post and vote on it.
It’s a bug not a feature request. I can’t save my file with wdsync since this bug happens…
WDSync stop on this file and doesn’t save the others…
As noted by init0, support article 11730 notes this is a limitation by design; not a bug. As such, changing its intended behavior should be treated as a feature request.
