I've been searching for a conversion program that can handle .imp files, and was really starting to despair that nothing like this existed! I've tried the GUI being developed here (can't find the thread...
), but had less-than-useful results so far.
After Googling for several days, looking at page-after-page of results, I found one that works, extracting the text to its own folder along with any jpgs (covers, maps, etc) that are included in the imp file.
Useful?
