Move a file instead of copying it

⌘ + X does not cut a file in the Finder, which is probably the most confusing gap for anyone arriving from Windows. The reason is that on a Mac you decide to move at the end, not at the beginning.

Copy the file with ⌘ + C, open the destination folder and press ⌥ + ⌘ + V. The file moves from its original location to the new one rather than being copied, and nothing is left behind.

The advantage over dragging is that the two folders never have to be visible at the same time, which matters on a laptop screen.

And ⌘ + X is not broken — inside a document it cuts whatever you have selected, exactly as you expect.
