Is it okay to delete Photos Library?
I'm struggling for space on my Mac and have sifted through iPhoto and deleted lots of photos only to find EVERYTHING is still on Photos. I don't use Photos and read that it's best not to delete it because it's part of the system. Is it okay to delete the Photos folder kept in Pictures? When I open the 'Photos Library' it just opens the Photos app. I can't find any clear answers and I guess I'm just paranoid about deleting things from my laptop so I'm sorry if you've had to answer this lots, I'm just pretty confused and worried I'll delete something important that is a necessity. Basically I'd just like to understand it a little more
Thanks for any help! I'm using a Macbook Pro and haven't updated due to the lack of space so am using the OS X Yosemite still if that's good to know.
EDIT: I usually use iPhoto
