Hi I needed to upload some children's cartoons while on a family trip to the lakes. Needed to hook it up for our child. iOS being iOS, I couldn't simply drag and drop it onto a folder, I had to put all the vids in a folder on my PC and sync it in iTunes. Trouble now is I can't delete the off. The X isn't visible. How do I get rid of them without going back home to my PC to unsync them? Any tools I can use to delete or some third party iOS file manger?
