Hi , bought a Nexus 7 for my daughter for christmas , but im having some trouble getting comic book files to view on the device. I have converted the pdf file to a cbz file and then moved the file from my laptop to a Root folder called COMICS on the device. However no mattter which comic book app i use , none seem to be able to see the file or if you try and change setting and get it to see the folder it is still unable to open the file. maybe i am missing something very basic.?i hve tried perfect view ,comicrack ,etc to name a few? any tips would be greatly appreciated.. thanks
