File transferring methods

Hi all, recently got my first apple product in awhile and was wondering the options to transfer files from my PC to ipad.

I know I can use iTunes, but are there any other ways of transferring large files with usb (e.g. no dropbox/icloud/etc.)? I read about a program called goodreaderusb.

I know if you jailbreak it (whenever that will be) that you can use iFile which you can transfer wirelessly which would be cool.

Thanks!
