Need help for exporting/converting iTunesU course materials to Windows PC
I attended some instructor-led courses last year, the courses' materials such as books, presentation, exercises, notes, web links were delivered using iTunesU. I also have audio recording of the classes which I made using VRP 7.
I made a mistake by upgrading my iPad 2 to iOS 8 as it made its performance really poor. Now my iPad 2 is at iOS 8.3 but still problematic.
I want to sell my iPad 2 therefore I am looking for a way to copy/transfer/export/convert the courses' materials to my Windows PC and then read it using standard applications such as MS Word, MS PowerPoint, etc without the need to buy another iPad.
I have installed the latest version of iTunes on my PC and run them, unfortunately I could not manage to copy/transfer/export the iTunesU materials. Using iTunes, somehow a few books are shown and I was able to export it to my PC, but the files have their name extension of .ibooks and I can not open it. Furthermore, looking at their file size differences it seems those are not the full courses' materials.
Additionally I could not find my audio recording files too
Later on I installed SynciOS but no luck, when I click on its iTunesU menu it says there is no iTunesU installed on my device.
Can anyone please help me how to do it?
