Copying files in Windows 7

When I was using Windows XP it had a very practical file copying system. I am a professor, change lots of documents for a class, and I could copy a folder on my hard drive over a folder on a flash drive--i.e. updating the folder on the flash drive--. Windows would ask me, essentially, if I wanted to replace older files with newer files. I would check yes, and away it would go for any given folder. The Windows 7 that I have does not seem to have this function. It makes me answer the question file by file, which is of course more time consuming. I have Windows Ultimate. Is there a way to solve this problem? Thanks.

 

You can also use a tool called Teracopy. It is free and gives you some additional info. Once installed it replaces the default windows copy program so its easy enough to use.
