Emacs dirtree resize partition

Question

I have dirtree working with emacs, its very good. The only issue I have with it is that I want to be able to resize the partition between the directory structure on the left and the file I am editing on the right.

I have done some googling around the issue but have not managed to find anything. I am new to emacs so the explanation may need to be in somewhat layman's terms.

Answer 1

GUI mode

Hover your mouse over the status line between the two windows, you can drag to resize.

Terminal or GUI mode

With the point in the dirtree buffer press C-{ to shrink the window or C-} to expand it. These commands work one column at a time, if you want to repeat it use C-x z. i.e.

C-{ C-x z z

to shrink by 3 columns.

To change the stepping, use a prefix argument

C-2 C-} C-x z z

will expand by 2 columns 3 times.
