The camera connection kit can only be used to import photo/video files from a camera, SD card or USB flash drive. You can't import other types of files. You can't export any type of files using the camera connection kit.
You can use a USB flash drive & the camera connection kit to import photo/video files.
Plug the USB flash drive into your computer & create a new folder titled DCIM. Then put your movie/photo files into the folder. The files must have a filename with exactly 8 characters long (no spaces) plus the file extension (i.e., my-movie.mov; DSCN0164.jpg).
Now plug the flash drive into the iPad using the camera connection kit. Open the Photos app, the movie/photo files should appear & you can import.
