I have my photos on a NAS, and the folders always are out of sync, I mean, I right-click and press Syncronize and always have all the photos for sync. In addition, when I send an image for being edited in Photoshop and save it in PS, instead of stack it with the original, LR creates another folder with the same name of the original in the root and put inside the photo. This happens even before I buy a NAS, and reinstall all the CC many times. Any ideas? I don't know what else to do. Thanks!!
