I did that. It was even bigger pain in the ass than I thought because the files are not alphabetically named. So when one file downloaded, I needed to rename it and add number before it. Didn’t want them to mix up. For each, file it was such a chore.
Because this is a fan-made project, each file has at the start and at the end ads for patreon, reddit and stuff like that. So I used some kind of mp3 trimmer to cut all of them automatically. It was not perfect but passable.
I might still have the files on some external hard drive, so if you give me some cloud shared folder or something I can upload it to you. I only know about free MEGA, but they have like 5 gigabytes limits and the book is like 11, If remember correctly.
Or alternatively, as I mentioned in the original post, you can use some podcast app like AntennaPod and listen there.
Oh shit, one of those losers is here.
