How to get only one Explorer panel on startup?

[Pohokano]

MC shows two panels ("windows"?). I can get rid of one of them by ctrl-F11. How to save this step to have only one show at startup? (I've searched the online documentation and this forum; perhaps I'm not using the correct terms).

You can't (Unless you do unrecommended workarounds and set the split with script that run at startup)

Because MC is designed around the dual panel layout where one panel is default source and the "other" panel is the default target. It is not designed to be a single panel filemanager like Windows Explorer..
Even if you hide the panel (F11) it is still there and many function in MC depends on it and by hiding it you might do things in the panel that you don't know is there. So to avoid you messing up files, it will now save a 100/0 panel split.

...up files, it will now save a 100/0 panel split.

...it will not save a 100/0 panel split.
