Marie,
Windows 7 has it similar to what Kahless said.
Click on "Organize" in the top left corner, select "Layout" and then "Details Pane". That will activate the bottom part as seen in Karsten's pictures.
For you backups, instead of going manually like now, I suggest you use a program that does this. Karsten said he uses something called "Beyond Compare" which I don't know. I use Microsoft's Synctoy which is free, easy to use and does the job for me.
