And why sony add no folder option?
Without the possibility to store books in folders the navigation with a dozen books is very bad. And what should a man do with a inserted SD card and with maybe 1000 books in one folder? Scrolling till dead?
The other one is, can I sort the books at any way to filenames?
I got a lot of PDFs who the informations are not stored 100% correct inside and the sorting is not correct then.
