I'm not a fan of this. Aside from it being a maintenance issue (editing the SSIS package every time a new folder is needed or removed), you could at least use a for each task and iterate over a list of directories. Inside of that loop, you could use expressions within a file task to copy it around.
It's still good as a teaching exercise. In practice it might be better to have a scratch location for the master and then read the destinations from some table. If you are going in for the script task (VB or C#) then take a closer look into the File I/O objects. I seem to remember that you can specify overwrite or not.
