Open new file in a new gui window or by splitting the window

Question

How can emacs open a new file in a new gui window? And how can it be made to open by splitting a window?

Answer 1

Emacs refers to gui windows as 'frames', and the partitions with a frame are called 'windows'.

You can open a file in a new frame with C-x 5 f. You can open a file in a different window in the same frame with C-x 4 f.
