So I found this thread:
https://www.mobileread.com/forums/sho...d.php?t=159439
Talks about an app called Relaunch which I am guessing is like root explorer but can open the books up? It may be my answer
I'll look more into it.
The thread also mentioned that some ebook files have tags. I'm not sure which formats use tags and which don't. I'm pretty sure all don't and neither do .jpgs. So tags doesn't seem like the answer for me. I'll look more into that too I guess.
If anyone has another solution they deem better, please let me know.
