Copying one file to a new file

I know this may be trivial but it's been a while since I coded and vb isn't documented as well as Java :(

I was wondering what the code would look like to create a folder called "temp" in my c drive. So the path after created would be c:\temp.

Then I want to copy the contents from a folder named temp1 to temp (just a copy, I want them to exist in both places temp and temp1)? I can do this via command line but thought it would be easier to write an exe that will do it.

Thanks for any help in advance.

You'd use these:
io.directory.createdirectory()
io.file.copy()
