The CVS is a more complete update, but for those users just interested in the clean VB code, here it is. Have fun with it!
I have released the source code of the last official (beta) version of MultiEx Commander, 3.9.68 that should act as starting point from where new open source versions may arise! Note that the source code of version 3.9.68 may not be compiled and distributed as binaries, without permission of XeNTaX (http://www.xentax.com), because it is part of the official setup file available. When the source code has been impoved/altered however, that's a different story, because there's no version conflict then. Feel free to download the CVS and join the open source project!
