Question Moving files from external card to internal

Hello all, I did a search and did not find what I was looking for.

I'm a noob to Android coming from iPhone and Blackberry, but I love it so far.(Also note that I have enabled SU permission and side-loading apps from the great instructions here)

I just want to know how to transfer my music, pics, and movies from my micro SDHC card to my internal storage? I tried dragging and dropping from Samsung Kies, received a move error. Then I tried using Astro File Manager and received the same error.

I must be doing something wrong here....

Thank you in advance
