Dear Wallcraft,
Thank you for your answer.
However SunriseXP is not able to handle https: pages. Failed:"Internet connection is offline" or in update log
"notHandled: 4294967295 an SSL-enabled server port.<br />"
Because of your answer I tried Plucker-Desktop again, not with the build-in browser but IE7. Now I got a browsable .pdb copy! The result however lacks the original web layout aswell as the link icons are not allways placed and displayed correctly.
The best web copy results I got from Teleport Pro (however no https

, Webcloner and wget in Linux. The reason is that they copy the web sites exactly and do not make their own interpretation. Only wget is freeware.
Thus I still stick with a nice set of copied (sub-)directories, 100% perfect on my laptop, but because of the "/C/" issue worthless for the Dillo or Midori browsers.
PS: Minimo is OK for https pages!
But for offline browsing also can't handle the "/C" in the link path.
