There's pleant of back-p software around, including some free stuff. But frankly, all you need is a small batch file. Assuming the files you want to store are in folder c:\myfiles and your CD drive is D:, your batch file would read
erase d:\*.* /s/q
xcopy c:\myfiles\*.* /e d:\myfiles\*.*
or you casn simply drag the files in My computer.
