No... I don't think emailing will help anything...

Are you saying you can not create new folders to the memory card, or that you can not copy files from your PC to the memory card?

Just to make sure you do have your N810 tablet hooked up to a PC via USB cable. You should see the N810 2GB internal memory card as Removable Disk. Correct?

Procedure to create folders on memory card is the same as you were creating folder on your computer hard disk. (Like if you are in Windows File Manger in C:\ root, you just click File menu, select New, and then Folder... and there you go.) The only difference is that you need to open the Removable drive instead of local (C:\) drive.

Copying media files is just a simple Copy/paste, or Drag-n-Drop operation that you should be familiar with if you ever worked with computers in general.
