I don’t have an SD card in the phone.
Makes me curious about the parameters that the app will accept when it comes to find epubs to catalogue and render?
Is it only via an SD card - which would be absurd, as why would you rationally ignore the internal storage which [will] be present, for something which [may] be present?
Is it principally on the internal storage, provided you use a folder on root with the name of “Books” - but if you blank it out it will scan external storage?
Is it any folder on internal storage, provided you rename the folder you want the app to look for - i.e. me fruitlessly changing it to “Documents” which is where i dropped by ebook subfolders?
Is it simply that the app hates subfolders, and demands that epubs are in the root of whatever folder you use for books - i have a lot so i keep them in Author named subfolders?
Right now i don’t know, as i can’t find a permuation that will find books at all? As file-transfer via USB cut-out before i can move my GB+ collection of subfolders, and I lack an external SD card.
