CDisplayEx is a comprehensive and feature-packed comic reader.
The program can import plenty of formats, including CBR, CBZ, CBT, CB7, all the equivalent archives, PDFs and even regular image files.
There are a pile of viewing options. You might start by switching from single to double page, with an optional shadow between pages so it looks like a real comic. You're also able to rotate single or all pages; fit pages to the screen, their width or height; set a zoom factor, use a magnifier and more.
You might navigate through the pages with just the left and right arrows. But PageUp and PageDown also work. If you prefer a mouse, the toolbar has First/ Previous/ Next/ Last buttons. And you can use a slider. Or double-click page thumbnails. Or even have each page displayed automatically in a slideshow.
If you don't have time to read a file in one sitting, that's no problem. A "Resume Last File" opens it where you left off last time. There's a File > Resume Recent list if you're switching between several comics, or you can use Bookmarks to save a favourite page for easy access later.
The program even has an optional Explorer extension which displays the cover of a comic when you're viewing it as an icon.
Please note, CDisplayEx will by default try to install other applications as well as its own code. Pay close attention during setup and make sure you only install the components you need.
An excellent comic viewer, with wide file format support and a host of viewing and navigation options.
