Okay, not sure which version of Daisy I'm working with here, but here's the output from ls on the root of one of the magazines: asimovs_2018-11-0001.3gp asimovs_2018-11-0002.3gp asimovs_2018-11-0003.3gp asimovs_2018-11-0004.3gp asimovs_2018-11-0005.3gp asimovs_2018-11-0006.3gp asimovs_2018-11-0007.3gp asimovs_2018-11-0008.3gp asimovs_2018-11-0009.3gp asimovs_2018-11.ncx asimovs_2018-11.opf asimovs_2018-11.pncx asimovs_2018-11.ppf asimovs_2018-11.smil asimovs_2018-11ann.3gp asimovs_2018-11hdgs.3gp asimovs_2018-11pdtb.md5 dtbsmil110.dtd ncx110.dtd oeb1.ent oebpkg101.dtd pdtb_protected.smil protected.mp3 us-nls-dm-asimovs_2018-11.ao I don't recognize most of the filename extensions, but I suspect the .3GP files are the actual audio since du -sh * | sort -h identifies them as being the largest files in the directory. I also know protected.mp3 is simply a recording that plays when trying to play the book on a unauthrized device. I'm assuming most, if not all, of my current Daisy Library is the same major revision of the format as most of the magazines are dated 2017 or 2018, and there are five files that Jdupes identifies as being identical across 137 audiobooks, which I believe is the entire library. I hope that helps others in narrowing down exactly which beast we're dealing with. -- Sincerely, Jeffery Wright Bachelor of Computer Science President Emeritus, Nu Nu Chapter, Phi Theta Kappa. _______________________________________________ Blinux-list mailing list Blinux-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/blinux-list
