Surfing yesterday I found this little free app that allows windows explorer to preview raw files, it's free and it supports Mamiya and Hasselblad, I had another one installed form canon (there is also another one from Microsoft), but this one supports the ZD files which is what I was looking for. Better than having to use third-party programs to just surf the folder. Thought it could be helpful for others so here I leave it.

P.D. I'm not affiliated with this brand or program in anyway, moreover it's free.
