I loved Directory Opus. I have never found another file manager that even comes close.

While I should like Directory Opus 5 onwards (inc the Windows ones), v4 was the bees knees for me. So I stuck with it.

And here is my config file for you to obtain, use, and abuse. (Hosted on mega.nz)

This configuration file was created for Directory Opus 4.12 many years ago on my Amiga 500 Plus (with GVPA530 030)

I setup buttons/banks for all the mainstream archives I was dealing with at the time, and multimedia playback for “PC” files.

Hope you find it of use, even if just to steal command lines from it.
