Transferring Photos from System Library to External Drive Library
For a very long time I've been (successfully!) transferring photos from the system library on my MacBook Air to a photo library on my external drive, as follows:
- Open the System Photo Library, select 'all', export to a folder, I delete all the photos from this library and then close it
- Open the External Drive Photo Library, then the Import window
- Open the folder with all the exported photos, select 'all' then drag and drop into the Import window
- The little circle spins around and then all the photos appear as imported with todays date
However today - despite doing everything exactly the same - I received the error "Cannot import 389 items. Some items cannot be added to your Photo library because they may be an unrecognisable file format or the file may not contain valid data".
My files are .jpeg and .mov like they always are. I did nothing different in my process. My External Dive Photo Library is showing everything perfectly up until the last successful import.
The strange thing is that I can successfully import todays folder of 389 items back into the Systems Photo Library - presumably if the file format is 'unrecognisable' or the files doesn't 'contain valid data' this would not be possible.
I'd be most grateful for any kind advice. Many thanks ☺️
