After your post I have been testing other browsers:

Raw Therapee works but it is slower than Konwertor.

XinView (latest version) doesn't support .rwz file extension; there is information about supporting in change log but in associations menu i can't find appropriate switch.

More over I tested Rawzor SDK with example program and I noticed that there wasn't any difference between extracting method in file weight (tested on Sony Alpha .arw file) – so I still suppose that browser firstly decompress .rwz file for extracting embedded .jpg from .arw (maybe it's only problem with Sony extension).

First of all I am very glad for Your fast reply and of course your work of Rawzor. In my opinion this project fulfill the gap in the lossless raw-compression standard.

For me the thumbnails aren't really important because I work with Total Commander as a shell manager. But I still need a simple and fast way to browse my photos without extracting it. Before I decided to post my idea I had tried browsers supported Rawzore extension and they had been working to slow for me. I suppose this statement is connected with methods provided in SDK. I notice that browsers should decompress raw file to have a possibility of previewing embedded image from the native .raw. When I use Konvertor to preview 100 photos compressed in Rawzor from DVD-Ram it's simply crash.

Adding a small jpeg image to the beginning of .rwz file provide a better compatibility with other browsers, users can use they favorite software and give them a chance to find desirable photo to work with in very short time. After that they still should decompress the correct one to work with they favorite post-processing software.
As a salvation of this problem you can extract embedded preview image from raw, shrink it (half resolution and medium jpeg compression = less than 100 KB) and add it as a header of the .rwz file.

I suppose that many Rawzor user will be sympathize with this idea because it's providing a very fast way to browse photos in favorite software without necessity of creating sophisticated plugins.
