CBReader

I keep my comics organized on my micro SD card and read them directly off the card through this app. It maintains the folder hierarchy so I stay organized which is the most important thing I look for in a comic book reader.

Each time you ask the program to refresh the library, it kept creating a new copy of the file, so a comic will show 3, 4, or as many times as you have set to refresh the library.

This is a servicable Windows app but it doesn't beat things like Modern Comic Reader on Android or Chunky on iOS. Chunky in particular has nice features like connecting to a cloud service or turning the device into a file server to pull down comics. Once those comics are on the device it will automatically make collections for you. Just make sure you've named the files correctly and it works very well. Reading is largely the same between any of these where they put in effort so it's really the organizational aspects that really need to stand out. This app could use a refresh in that regard. This also makes things like tracking read/unread easier.
