Thanks to the forum for this one. It looks like some bright spark has managed to connect up a USB Drive to their Nexus 7 via an OTG Cable. This has been done before of course, but this time it’s been achieved without rooting the tablet!
After installing this app you’ll be able to import and stream music, video and photos from a USB flash drive or SD card connected to your tablet.
You can find out more from this clip:
If you want to trial the concept, have a go with the free sister app. It won’t allow you to import music and movies but it will give you a feel for whether this app will work for you.
Note: this allows you to import / stream content from your USB drive, but it won’t allow you to copy data the other way.
