Would appreciate it if someone could tell me how to either download all my photos from OneDrive - about 85,000 - and / or sync Onedrive Photos to a QNAP NAS.

I have tried all the alternatives but due to the number of photos the clicking / selecting folders and photos does not work with the volumes I have.

The Desktop Onedrive app will only allow 100 photos to be selected at a time so this is no good either.

Thanks
