Thanks a lot for addressing a cruel lack in NextZXOS !
I had first tried using the early versions of Calm Commander years ago, and it messed up the destination, so I was out of solutions.
I guess it's all fixed and operational in Calm Commander now ? A few weeks ago, you started to indicate multiple files selection was now working, but I was unsure about whole folders and subfolders, I'm happy you can now, meaning Calm Commander will become very useful. :)
