Hi Ladyluck and Good Morning!
Don't worry too much about the long estimated download time. This often happens and is often caused by a number of people all trying to download a driver at he same time. Just give it another go and it will probably be fine!
I'm inclined to agrre with Golden that your "duplicate" file issue is a Libraries misunderstanding. It is confusing when you set up a new library and then get invited to "Add a folder" That's when you get what shows in your screenshot. Remember that what you see in the Library is not a duplicate copy of the file but a link to the Folder where you saved the file to. So when it looks like a duplicate file it isn't. It is a duplicate link to the same file. Libraries are explained much better than I can here:

Well worth a read when you have time!!
Once you get used to the Libraries their value becomes apparent. IMHO it is one of the best innovations of Win 7.
