same as tho it where the mSD card?
Yep, once the drivers are installed the phone should show up in My Computer, you will have the choice of "Phone" or "Card" just go into phone and create yourself a music folder if there isn't already one there (I don't remember if there was one there as default) and copy music over, same with videos.
Once you unplug the device the media scan should run and pick up all the files you transfered, if your using Poweramp you may have to specify the folder where you have copied the music to.
