I'm trying to free up space on my hard drive for my Mac Book Pro 2010 2.4 core duo 4 GB ram and250 GB HD and I want to delete my iPhoto directory. The iPhoto folder says it has 66 GB of data. I confirmed that my photos have migrated to Photo app. so I want to delete this folder. Is it possible that even if I delete this folder that it won't clear up any space as the file is a directory to photos stored on the HD. I don't intent to use iPhoto software in the future but that is one reason to keep the folder?
