I use Cool Reader to view most of my eBooks because it is the most compatible reader I could find (I have a mutt library). It is also easy to navigate and read, unlike apps like Mantano which have tiny useless buttons all over the place. I don't use Adilko because it forces the user to import books into its library, effectively requiring double the space for eBooks: space for my hand-sorted eBook library, and space for its own library. I use BeamReader to view my PDFs because it's the only app I've found that has a text wrap feature. I haven't picked out a comic viewer yet.
I am looking for a browser that can open all non-PDF books in Cool Reader, PDFs in BeamReader, and comics in a comic viewer. I have tried using Root Explorer to open books, but it only works with BeamReader for PDFs. I think it opens .txt files in its own reader.
Is there any single file browser I can use to open all of my eBooks? I'm open to both free and paid options.
