How to use camera connector kit to transfer files and photos?

You can only use the kit to copy photos and videos to the Photos app on the iPad - it doesn't support other file types nor the copying of content off the iPad. In order to copy photos and videos to the Photos app, you need to create a DCIM directory off the root of the card with the photos underneath it, and the photo filenames need to be exactly 8 characters long (no spaces) plus the file extension i.e. in a similar format as if a camera had created/written them. You can't copy films/tv shows from iTunes via this route (they'll copy to the Photos app but they won't play).

For PDFs you can sync them to the iBooks app on the iPad (if you've downloaded it) via the Books tab when conencted to your computer's iTunes. Other PDF apps may use the file sharing section at the bottom of the device's apps tab when connected to iTunes, via wifi, email, dropbox etc

To copy photos off the iPad that you've copied to it via the kit, then you can use your computer : photos to computer.

Connect your iPad to your computer and and select the iPad on the left-hand side of your computer's iTunes, and on the right-hand side there should be a series of tabs, one of which should be Photos. Select that tab and at the top of it you can select to sync folders, and select the 'parent' folder under which are the sub-folders that you want to sync to the iPad. Each of those sub-folders should then get their own album on the iPad - the albums only work to one-level i.e. if you select the 'My Pictures' folder at the top of that tab, then only the folders directly below it will get their own album on the iPad - any photos in sub-folders below them will be included in their parent's album.

There is a (little) bit of info on this page : http://support.apple.com/kb/HT4236

Also note that you will need to sync all the photos that you want on the iPad together in one go as only the most recent photo sync remains on the iPad - synced photos can't be deleted directly on the iPad, they are instead deleted by not including them in the next photo sync.

You can use a USB flash drive & the camera connection kit. I use this method frequently. If your flash drive uses too much power, get a new one.

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. (You can not export using the camera connection kit.)

Effectively you are just creating pointers to those photos in the new albums, it's not copying them - so if you then delete the original photo (and photos synced from your computer can only be deleted by de-selecting them on your computer and re-syncing, they can't be deleted directly on the iPad) you will also be deleting all pointers to it.

Use the Camera Connection Kit to transfer photos from SD cards and directly from your camera.

To transfer other PDF and video files use the sync method with your computer. It's easy and fast.
