A Macro to create and save a new workbook with the first few sheets of the current workbook?

I have a pretty big workbook, and currently it has 8 hidden sheets. There's a lot of data in those hidden sheets, so the size of the file is pretty big.

What I'd like to do is have a macro that creates a new file containing the first few (5) sheets of the current file I am working on. I'd like the sheets to be copied, not moved, to the new file. The name of the new file could be the same as the one I'm working on, with an extra letter or number at the end.

Does someone have code that can do this?

Thanks!
