Viewing Composite Document File V2 Documents Every now and then I receive attachments from Windows users that show up as "Picture (Device independent Bitmap)" and - when I run "file" on the command line, they are identified as "Composite Document File V2 Document".

I guess they are screenshots - what would be the best way to view them on a Mac?

Thanks.
Based on the output from file I'd suggest that you try unoconv to convert it to something your system can open.
