I downloaded Droid Explorer correctly, Busy Box and can view my files (on my Android device) .. but when I select the file to copy how can I drop it on to my PC drive?
There are a couple ways to accomplish this.
You select the files (folders are currently not supported) and click the "copy to PC" toolbar button.
The other is to select the files (folders are currently not supported) and right click and click "copy". Then paste the files to your desired location.
There are plans to attempt to allow for dragging and dropping, but I do not have a timeline.
