How can I search for *.exr extension?

Hello,

my render engine always outputs in a very convoluted, non-adaptable file structure. So, after a night of rendering, I usually windows-search for *.exr and copy from the results. But I'd like to preview and rename first in Bridge, so I can keep the folder structure (various render passes) and don't have duplicate data.

How can I find *exr with Bridge? Except searching for 32 Bit colour depth.

Thanks!
