Once photos have been migrated to iPhoto, is it save to delete the migrated folder?
I'm finding the need to delete old files and I see under storage a huge old iPhoto Library file that cannot be opened as it says "The content of the iPhoto library “iPhoto Library” has already been migrated to Photos. Open Photos to view your library or use a compatible version of iPhoto to open this iPhoto library."
Is it safe to assume these migrate photos are duplicated and I can delete this old file? Or do I need to keep the migrated "iPhoto Library" folder?
Thanks!
