/home/user/MyDocs. If you cd into there from Terminal and do an ls, you won't see all the subfolders you're expecting to because they are hidden (start with a dot), e.g. .documents, .images, .sounds. Personally, on the N810 I use the internal MMC (/media/mmc2) for all my data storage, because /home/user/MyDocs is in the 256MB limited rootfs.
