JeffMatt's advice doesn't seem relevant to your situation. It only applies if you're seeking to rip files from an audio disk but you seem to have simply saved the files to a data disk.
You obviously know how to get to your 'My Music' folder, so do that first. If the contents of that folder are shown in a full-screen window click on the 'restore down' button (next to the 'close' button at the top right of your screen). You'll now have a window which can be resized by clicking and dragging on the edges of it. Make it so it takes up about half of your screen.
Now place your disk into the drive. Double-click on that drive's icon, to display the contents of the disk. Resize that window as well, so that you've got the two windows side by side. In this second window go to Edit and click on 'Select All'.
Now click on any file in that second window and, keeping the mouse button held down, drag it across to the first window. Job done.
