So I updated my OS to 4.5.0.81, and had less memory available than others had. I had only installed the en version of the DocsToGoCommonResource_xx.cod. But I downloaded the upgrade. And to check what was using memory, I check the modules.

In going through the modules to see what's taking up space I see:

SheetToGoResource
SheetToGoResource__de
SheetToGoResource__en
SheetToGoResource__es
SheetToGoResource__fr
SheetToGoResource__it

Their sizes are:
de 10,904
es 10,960
fr 10,956
it 10,812

So that's 43,632 extra space just on the Sheets to Go.

But there's also the same for:
DocsToGoCommonResource
SlideshowToGoResource
WordToGoResource

When I tried to delete Docs to Go Italian it says it's in use, so apparenty I was using it in Italian even though only en modules are installed for everything else. It did delete on the second attempt.
