Connectivity - usb cable

I've just bought this phone, and when i plug the usb cable into my computer, the icon comes up on the screen but whenever i drag files in to it, they don't appear on my phone...WHAT SHALL I DO??

Hi shannon, have you tried, transfer music, then search music files on pc, then when files are found they have to be converted to mobile phone format before transfer

Im not a genius or anything but i have nokia pc suite and i cant drag files to my phone either. i usually just plug the memory card into the computer and it comes up as a memory card with the images and video clips folders etc. im pretty sure its faster than the usb cable. you could also buy a usb infrared thing but they are very slow to transfer files. so if you really want to use your usb cable then this question wouldnt've helpd. thanks.
