Reading a magazine with CDisplayEx.

CDisplayEx is a document reader for Android and Windows which is designed to view compressed image archives that commonly used by comic books, magazines, and e-books. It is based on CDisplay, a similar program whose source code was lost when the developer died. The Windows version is free, but no longer being maintained. The Android version has a "Lite" version which is crippleware and a "premium" version which is commercial.

In the 2000s, had downloaded some comics which came in CBR format, which I didn't recognize. I did a quick search online and found either CDisplay or CDisplayEx (I don't remember which) to view the comics. I also realized CBR files are just RAR files with an alternate extension, so I could decompress the images and view them in any graphic viewer I wanted, but, after seeing all the features in the program, I opted to use it to read the comics.
