I hope I'm not intruding here on this thread, since my device isn't Nook but it is an Android device. I've been trying out Moon+ Reader and it looks like a good app, especially since now it seems to me to support more formats than it did last time I tried it.
There are two things I'm wondering about:
1. what exactly does import mean? does it actually make a copy of the books I import into it? There doesn't seem to be any user manual on the developer's website.
2. If so, how can I do a batch remove of the books I imported? Right now it seems that I can only do it one by one, and I foolishly imported a folder with my fanfic containing four different fandoms and thousands of fics (it tells me I have 2190 books). Since most of them are txt files, they have no tags and a lot of them appear without any information other than file name.
