I use optimized versions that I store on my WD Wireless Pro. I recently “optimized” nearly 2 TB of movies to it and all was well. It has been a couple weeks since the WD was connected to my PC, but I just noticed all these TV shows being dropped on a HDD location they shouldn’t be.
When I looked at the config for the optimized version…one changed to “in folders with original items” and the other “D:\TV Shows”. Neither are correct or the location that was originally configured. I can’t change this so I don’t know what my options are to fix it.
