How on earth do I move files from Google Drive somewhere else without deleting it?(solved, thanks!)

I am out of space on my google drive and I probably am missing important emails and I can't send anything out. I don't want to delete my files. but I don't see any option at all to transfer to an external hard drive or another cloud like iCloud. Can someone please help me?! I've been dealing with this for months now!

EDIT: THANKS, EVERYBODY!!! QUESTION SOLVED! too bad I can't give "best answer" to everyone!
