iPhoto & Photos library
I recently moved my entire iPhoto library to Photos and now I have two photolibary files: one for iPhoto and one for Photos. Both are 70+ GB. My MacBook only has a 250GB hard drive and is 9 years old, I'd like to free up some disk space.
I know that for some files Photos links back to the iPhoto library so I can't just delete it, but I've checked and that doesn't always seem to be the case. Some files have been copied and those doubles are taking up a lot of space.
What's the best way to resolve things? What will happen to the file in Photos if I delete it in iPhoto? Should I go through my entire Photos library manually and transfer the files that are linked, so I can delete the iPhoto library? I'm not sure how to proceed...
