This is another of those situations where the solution to the problem is obvious once you've been told where to look!
Thanks, the reply above certainly helped me.
On the ViewPad7, connect to your PC and
select 'Settings'
Hit SD card & phone storage
Hit 'Unmount SD card' then 'OK'
On the VP7 screeen you'll see the indication has changed to 'Mount SD card'.
"Pull" down the menu under that screen and you'll see 'USB connected: Select to copy files to/from your computer' - hit there and you'll go to another screen where the Android character has turned green you'll see a message telling you 'USB connected' - follow the instructions shown and the Android turns to red.
You can simply drag and drop files across from your PC to whatever drive your VP7 in on.
Just follow the instruction to reverse the op and start reading the files on your tablet.
