This may not be the correct spot to ask, but here it goes.
I'm trying to eliminate Calibre-Companion since it is abandon-ware.
I bought a new SD card for my Likebooks Mars.
I prefer Moonreader+ over the built-in reader for how it organizes my books.
I connected my likebook-mars via cable to calibre on my computer. I can transfer books to SDcard/books just fine.
Bouye's built-in can find them without any problem. Moonreader+ can't even see them, much less import them. Everything is in epub format.
I also removed the card and tried transferring to the card when directly plugged into the computer. Again Mars was fine. Moonreader is not. Uninstalled and reinstalled it to see if it makes a difference, but no.
Any idea what might be going on with moonreader?
