Open your kobo app using the Library icon, tap the Home button at the bottom of the Vox, and tap Import Content, then Start and the app will search for the ebooks you just copied to your SD card. Select the ones you want to import and voila! You can read them in the Kobo app. I was able to move several books I had put into Aldiko into the Kobo app to read...
Hope this helps!
