Just noticed yesterday that when I connect iPad to my computer, go to Apps in iTunes and VLC documents (same for other apps, e.g., Noterize), there's a Inbox folder that has been added, in addition to my other files.
In that folder seems to be the video files that I've opened (with iPad) from the Mail app. Each time I open a new one, they add it to that folder, taking up storage space.
Problem is, I can't seem to be able to delete that folder.
Thks for your help.
