To create a new folder, select the menus FILE > NEW > FOLDER.
Then click on the folder (New Folder) and select FILE > RENAME to change the name of the folder.
You can have folder within folders, and this allows you a great deal of
flexibility in organizing you papers and assignments. Here is a folder structure that a typical student might have.

If you need to move information to a subfolder, you can click on the filename and drag it to the folder (You can also do this to move folders around).
To COPY to another drive (such as a FLASH/JUMP DRIVE) you can drag the folder to the DRIVE device. If you drag items to a different DRIVE letter - it creates a COPY of the files there (and leaves the original files alone).
