I was trying to figure out a command line with 'copy move' myself. It didn't work, so I went into Opus F1 Help, tab 'Search', entered copy move and found the item "Copying, Moving and Deleting Files".
Nothing with "Copy Move'. Okay, go to File Operations then. Nothing there. Needed examples with 'copy move'.... and just to try to sort things out myself, before asking here. Gave up. Downloaded the manual (PDF) and searched for Copy Move. Regretfully no examples there either.
Feel a bit like newbie asking how the command line would read for what I have in the Opus context menu, viz.move to x:\folder
i.e. tried : \Directory Opus\dopusrt.exe" /cmd Copy Move TO "X:\Folder\") but that did not work.
