Use Windows Explorer to copy them into relevant
folders
You can add new folders and subfolders if
you wish as long as you maintain

Backgrounds,
Images,
Sounds and
Videos
You may make a collection of mixed resources and
place them in a folder for your project. A class doing a
project on animals could use an animals resource folder inside the clipart
folder. Each student then would take the resources as they need them
rather than copy them all into there work directory incase they might need
them.
