I believe the phone also comes with a program called "File Commander". To use this go into "Apps", then "File Commander". Next tap "Internal storage" and finally "Pictures", "DCIM", "Music", "Movies", etc. Now go into the folder that has things you wish to move and select each item you want to move to the card. Then tap "Copy". Now tap "Back" and then tap the name of your SD card.
NOTE: Don't use the "Cut" option. Why? Well, sometimes when that is used, and if the phone has any problems, get a call, etc. while doing the cut and then paste, the items are lost. It is better then to use "Copy" and then "Paste" to move the items. Especially when moving a bunch at a time.
Do this in each folder of items you wish to move.
To make specific...
