Firstly I know nothing about ipads and this is for a Christmas present.
My son has expressed a suggestion as a gift of an external hard drive to download the content of his ipad and free up space. He understands the type would need to be a WiFi unit and believes there is no compatibility with a standard USB connector to transfer data.
As I have searched Amazon and seen several customer reviews that indicate external hard drives which are claimed to be compatible fail to perform the function, can anyone either provide more information or recommend a unit which is guaranteed (preferably by experience) to perform correctly and simply with an ipad.
Kingston Technology 64GB Portable Storage Wi-Drive .
I use this one for all my tablets. There are more available of differing sizes.
Not sure if apple phones will connect, might be worth a search for confirmation
I have researched more and found quite a lot on various sites that indicates that external drives are quite limited in their use with ipad. As a result more information on some software which may enhance the function is being sought. For the moment I shall hold off spending the money.
The use of an external drive is still under consideration, but the use of File Browser (Ventad's link above) makes it look an easier proposition. However the question of uploading - especially large files (films etc) - is still a problem.
