I have a large collection of files packed into a two-level directory structure with many, many, many folders.
In other words, I have a folder with a great many subfolders in it. There are no subfolders in these subfolders, however, there are hundreds of files in them.
What I would like to do is move all the files out of these subfolders into the directory that holds the subfolders.
This is a limited resource system, so a way to do it without two copies of all these files having to exist at once would be amazing......
