Hi nrapallo, so glad to get your reply!
Sorry to be so late coming back.
Just as background, all I did was download the zip file for the IMP GUI Converter, and extracted that entire folder to my drive, then drilled down to the Debug / bin folder and launched the executable. It runs, I just don't know if I need to do anything else to get the html extraction to work.
One of the files I was trying was Zelda Pinwheel's "Jumping Frog" by Mark Twain, because I am doing that book in ePub, and wanted to see if she had restored the diacritics (I don't speak French). This is the link
I tried a couple of other IMP files as well, but can't remember titles just now.
I also googled unsuccessfully for a reader app that will display IMP files on my computer.
All I want to do is extract a reasonably clean text or html file that I can convert to ePub. Did I misunderstand what this tool does?
I will give a try to the other extraction tool you linked to, and see how that goes.
Thanks for the advice!
