So it looks like you changed the default storage location to folders you are managing yourself. If you use a file browser to navigate to your storage folder, do you see any of the PDFs under that folder or the subdirectories below it? Or are all of the PDFs now missing? Can you think of anything that might have occurred that would result in the files being deleted or moved? If you search for them on the device, do they show up anywhere else in the storage?
