Which vstsound files for which models?

Hi all.

Do the vstsound files correspond to models in terms of Close vs. Player or ECO vs. standard?

E.g. for the Steinway there are “D1” and “D2” filenames with three parts each.

I thought perhaps the “D2” set of files corresponded to the ECO version, but when I look at other models, the file sizes for the three parts are still quite large between the “1” and “2” sets. (The CP80 being an exception, as it’s just two files.)

I’m asking because I’d like to put the ECO versions on a rather cramped SSD, so I’d prefer to the move just the necessary files, assuming the files are broken out that way.
