So, I don't use iPhoto anymore. I've migrated my library to the newer 'Photos' app and I'm happy with it. Given that I'm almost certainly never going to go back to using iPhoto, can I delete the file called 'iPhoto Library' from the Pictures folder in Finder? It's taking up a considerable chunk of space so I'd like to get rid of it if it's of no use to me. Deleting it won't somehow **** up my Photos library will it?
