How do I move a folder in 10.9 Mavericks? I am trying to move a large (100GB+) folder from the Desktop into a subfolder on the Desktop. When I drag and drop, it invokes a copy, and I do not want to wait an hour while it goes through with this (I will need to do several such moves.) I have read that holding CMD while drag-dropping will invoke move, but it does not. If I wait for a folder to finish the alleged "move" operation, it turns out to be a copy, with the original folder left behind.

Interestingly, if I attempt to move (drag/drop) a smaller folder, it does so without issue. What am I doing wrong?
Open your terminal (Terminal.app)

Then do:

mv source_folder destination_folder

e.g:

mv /Users/foo/Music/ /Users/foo/something

This is way faster than copying as it maintains inode
