Thanks a lot!!!
It finally does work.
I am very gratefule to you two (opitzs and log) for taking your time with me and helping me.
In the end my last problem was to go to the right drive and execute the code there.
But now there seems to be a limit at how much is extracted, because it only extracted up to 200 characters; longer highlighted sections were not completely extracted....
Though one can live with this it is still annoying. Maybe this is more of a problem with the T1 than the code itself. Then again, the ebooks I use are DRM-free and should not cause such problems for the T1.
