Digital BW, The Print

With the Adobe Camera Raw converter out...which I like, I begin to 
wonder what people are archiving.

Original Scan when using a neg?
Last version?
Finished file - with and/or without curves if using them?

On the RAW field, saving the .crw file?  What about the .thm file?  I 
haven't explored what the .thm file is yet.

I figure I'll save things by category and incorporate date and/or 
the .crw file in the name.  Haven't thought it out completely yet.

Thanks for the input.
