windows - Moving files in sub-folder to main folders under many folders

My photo importing program puts the backup copy of the photos in a folder labeled "imported on DATE". These folders are created as subfolders of the desired location folder. I have many such "imported" folders under multiple layers of folders. An example would be:

C:\pictures\all photos 2013\01jan13\imported on jan 18.

Is there a way to scan down from the pictures folder through each of its subfolders and have the program move any files in an "imported on" folder to the folder above it?
Sorry if this is confusing!

Thanks for any help
