My aging Mac is unbearably slow to transfer data and a solution to just save the files from my Sinar back to DNG on Windows would be quite helpful (given that what is on the CompactFlash card is not usable except by the Sinar software). Years ago, Sinar was supposed to release their software program (more probably eXposure than Capture Shop) for Windows. I don't think it ever got past the beta, but I wonder if anyone ever got access to any beta version, and which backs it did support.
