Can I transfer RAW files?

I have a Nikon SLR. I have RAW files on the camera. When I transfer them to a folder on the computer, it converts it to jpg. Anyway to transfer without the conversion? I Want to keep raw files on my computer in order to edit them later.

Before you download the files you need to go to settings and indicate what type of file you want it downloaded as. You can't use a download program for this you will have to transfer the files manually.
