If you're a professional artist, then creating project directories can be a pain. I have an app for that, well, a work in progress :)
It's pretty simple really, scan your root content directory, select the folder(s) you want to clone for a new project, enter a name and press create. You can also add additional folders without creating a at a later date. No more manually, copying and or renaming or using shells or AppleScript etc...etc.
Anyway...checkout the video.
PS. This will work for any Directory Structure you have...like all of them :P
