Visual Studio 2013 uses the 'Save to multiple floppy disks' icon from long ago to represent 'Save All'
I am working on an application where I need to represent 'Save All' with an understood icon. What is a better method for representing it without losing the understanding of the difference between save and save all?
Edit
The context of the save is as such -
There are widgets within a page that each have their own ability to progressively 'save' information. At the top of the page there is a 'Save everything' button that should save all of the changes in the whole page.
