mrwul... I wasn't complaining or anything, I just found it funny that you posted a message asking if the feature would be better off built directly into Opus immediately after another post that announced "it's been built into Opus" - LOL.
Anyhow, I'd be more than happy to go over cleaning out your old buttons that aren't working for you, as well as to convert your .cmd file method with the built-in Opus feature for the copy/create folder maneuver... You can also check out Leo's and Gus's opus tutorials where they instruct on editing toolbars and such things if you want a good start on re-learning how to configure these things.
But for now, just let us know... how do you perform the Copy and create folder maneuver? Never mind the script for now... what do you do inside of Opus? Do you use a button, hotkey, or drag and drop maneuver? One benefit of using the recent built-in Opus method over the .cmd file script method we got from JohnZ is that a single <Ctrl+Z> keystroke will undo ALL of the files copied/moved... whereas the script file method will only undo one item at a time because each item (if multiple were selected) is being processed one at a time by the 'shift-ing' being done in the cmd script. Let's update your copy method first, then clean out the non-working buttons... but before you do ANYthing, just go to the Import and Export feature I mentioned above and save your current configuration to a file. If anythign get's whacked by mistake - it'll be a snap to put it back before continuing on...
