If you need to leave the original drawings in separate folders, just create shortcuts to the files (right-click on file > copy > paste shortcut). You could have a working folder on your desktop or wherever with all the shortcuts in it. Then, use the OPEN command in AutoCAD to go to the directory with all your shortcuts and open the entire batch at once.
