Am going to a friends house and was going to put films from my iPad on to her laptop to get films off but wounded it sync when I plug it in ?

And know a little window pops up afore iTunes like a windows thing(autoplay) saying view files but its this pictures you can take off the iPad

I don't believe that is doable.

Would using Dropbox work?

I've not used the facility for letting someone else see stuff in it, but the "Help" says you can.

Are the films in a third party video app or the Video app? There may be some hope with the former, but not the latter.
