Delete this left column in VIM
1 answer
I think this is the column that displays indicators for open and closed folds. Its width is controlled by a local local option 'foldcolumn'
(see :h 'fdc
).
By default, its value is 0
(disabled). If it is present in one of your windows, some file must have changed its value. To see which one you can run:
:verbose setlocal foldcolumn
+4
