Oh dear -- I didn't realise how much HTML etc I'd forgotten (or never really knew...). But, finally, here's a KM "make some folders" macro with an HTML front-end. It may not ever be useful, but it was a good learning experience.
You can set one or two ranges (either numbers, padded numbers, or letters) plus none, any or all of prefix, inter and postfix constants for your folders. The first and last folder names plus destination will be previewed at the bottom. So you could make folders "1" to "9", "01a test" thru "99z test", "test-01-project-A-folder" thru "test-99-project-Z-folder", etc.
The script will catch most of the problematic "special" shell characters, while letting you use spaces and similar. "Illegal" entries will have their field red-boxed to warn you. I haven't tried accented characters though! If you want to see the shell command that'll be used, remove the "--" at the beginning of the "display dialog" line in the AppleScript.
I would apologise for the horrible web page -- both the code and the look -- but I really can't be bothered!
