I bought my Libra H2O a few months ago. One of the things I was looking forward to the most was reading my backlog of comic books purchased through Humble Bundle. Much to my disappointment, most of the .cbz files I attempted to open would trigger an error saying that the file was corrupted.

I found the solution to this problem a few days ago, and came here to share! It turns out that .cbz files are nothing more than a .zip file containing an image for every page. Page arrangement works based on the alphabetic sort order of each image's file name. To get a large .cbz file to open, you need to reduce the file size of the embedded pages. In every case I've tried, simply resizing pages to fit within the Libra's screen without scaling is enough. I set them to gray-scale at the same time. The end result is that I am finally able to open these files. Even .cbz files that opened previously are able to turn pages faster.
