How to swap the buffers in 2 windows emacs

I am using emacs I find that sometimes I have 2 files separated into 2 windows.

For example: I open 1 file using C-x C-f file1.c RET

and I split the frame into two windows: C-x 3

I then open another file C-x C-f file2.c RET

So I have 2 files:

window 1 (left) file1.c

window 2 (right) file2.c

I am wondering if there is any key combination to swap the files over? Normally I like to work on the left window when I have 2 window. I know I can easily do C-x oto move the cursor to the right window.

However, I am just wondering if I can swap the files so that file2.c is in the left window and file1.c is in the right window?

In the Emacs 26.1 NEWS file there is the following entry:

+++
*** New command 'window-swap-states' swaps the states of two live
windows.

Which appears to offer similar functionality to crux-transpose-windows but can also do some height/width transpositions?

As current emacs 29 version. We have windmove , its like magic of swapping windows.

If you have prelude, you can use ace-window with S-w. From there you can do many things listed in their docs.

You can also start by calling ace-window and then decide to switch the action to delete or swap etc. By default the bindings are:

x - delete window

m - swap (move) window

c - split window fairly, either vertically or horizontally

v - split window vertically

b - split window horizontally

n - select the previous window

...

So it would be S-w m

If you use Ace window, which I highly recommend, you can swap buffers with ace-swap-window.
