after moving photos to an external drive and deleting photos on the hard drive my available hard drive space hasn't changed.. help
i am new to apple and a macbook pro, this weekend i took a lot of photos and imported them to the macbook and as I was running out of space I moved them to an external drive and then deleted them from the laptop, emptied the trash and I still only have 7gb of available space on the drive which is the same as before I deleted them... any ideas?
MacBook Pro with Retina display, OS X Yosemite (10.10.5)
