Noob question: click+drag

Try using a USB mouse, it works great.

 

The bottom section of the trackpad (I guess about the bottom 1/3) is separated from the rest.

I would put my thumb at the bottom and lay it on its side, and use my index finger to point.

So... kind of try to use it like any other laptop.

MS Paint Example:

 

Click on the folder/application or what ever you want to move and just move your finger while holding down.

Or you can just do it the easy way and press on the icon with 2 fingers at a time and copying.

 

You could also try turning on tap-to-click in preferences. Then you double tap and hold to drag something around. There's also a drag-lock preference, I'm not fond of it but it might be worth a shot.

If you really don't like tap-to-click then try as others have said and click with your thumb and use your index finger to move the cursor.
