In several version of iTunes- it seems to slow down or lockup if you select more than a few hundred files. So select about 200 or 300 files using the shift key, perhaps A-C files, then drag the files to a folder on your computer. Repeat for the rest of the files. Now you have a complete backup that you can drag back to your iPad should you need to. (Note: on OS X and the latest iTunes I have not had this happen for a while).
Also see the app DiskAid for copying files.
