While trying to sync my new Ipad2 to a new computer, I lost many files on my IPad. I do not see those files on the desk top computer either. Where are the files gone and how I can retrieve them. I am new to syncing.
Thanks.
If you did not create a backup in iTunes and made sure all your media was Transferred to iTunes first, then it is gone. Even then, there are some files and media that need to be saved separately.
This is the most complete list of preparations for transferring your stuff to a new device I've seen. While it isn't exactly what you need to move to a new computer, it covers almost everything you should do, including the all important Transfer Purchases, which bypasses iTunes usual erase and sync approach to a new computer.
