I tried Directory Opus and really like it, though there are two regressions that make me use windows explorer again. They might seem laughable to some, but for me if I have to switch to explorer the whole point of Opus is lost to me.
- Libraries are great for joining folders into a virtual one, but the "Open With" right click option is broken: If you don't choose one of the offered programs but "choose default program..." do copies the file to a temporary folder before the dialog is shown. I'm sure this is some kind of Windows quirk, but this is annoying if trying to play a 10gb media file with a different player :-\ ... Opus should just switch to the non-virtual real filesystem folder and then do the procedure without copying the file.
(The other point has been moved into a separate thread.)
