Referenced files in Photos
I've imported several thousand photos into Photos, and not realised that I wasn't creating a copy in the System Library.
I can view and edit them, but when trying to export for use elsewhere, I get the "The volume for “x.jpg” cannot be found" message.
Is this an expected response? Photos clearly knows where the file is stored, lets me edit and then appears to forget where it is.
I've tried to understand this, but frustratingly I can't.
Would appreciate any help here,
Thanks
