Excel 2002: Can I save all files in one go without exiting ?

[Mr. Low]

Dear Sir,

Is there a way to save all the files in the open window by clicking a single
button without exiting ? Frequently I need to save several files while
working on them.

At prersent, I can only see a "Save All" button while exiting Excel.

Also while exiting can I exit witout saving all the files by a single button
?

Current if I do not wish to save all the files, I need to click no one by one.
It is a bit time consuming.

I would be glad if you could adfvise me on this area.

Thanks

Low
