TOPAZ ebooks usually have the .azw1 filename extension.
Topaz files can also have the extension .tpz. And no one has 'cracked' the DRM on Topaz yet, to my knowledge. At least one person has cracked the basic file structure, but I don't think any DRM cracking will occur until enough .tpz/azw1 files hit the market.
