Avoid multiple upload of pictures

Hi there,
I have uploaded all my pictures from my IPhone (round about 9.000) and now did some sorting on my MYCLOUDEX2ULTRA. As I moved the pictures out of the folder specified for the mobile upload I realized 2 days later that the My Cloud App again started to upload all the pictures. Is there a way that the app remembers which pics have been already uploaded eventhough they are not in the defined folder anymore?

There must be a way otherwise I do not see the benefit to have thousands of pictures without any sorting (e.g. for years and month own folders, or per event,…) in one folder

@Mase The auto backup feature on Android and iOS will sync content from your mobile phone to the My Cloud so that all the content on your device remains backed up and safe. If content from the mobile phone is added to the My Cloud auto backup folder, and later deleted from the folder , the auto backup will add the same content back to the My Cloud as long as it resides on the mobile device.

If you move the content out of the auto backup folder, the OS 5 app will sync the content again.

Thanks for your quick reply.
That is unfortunately a pity as I thought I could use the NAS system as my Home Cloud to save the data and structure it accordingly.
Is it planned to get a function to be turned on /off to use the log file to see which files already have been synched and which are to be synched?
