If you’ve been downloading comics books from the internet, you may have come across some strange file extensions such as .CBR, .CBZ, .CB7, .CBT and .CBA. These are basically comic book archives. Each page of a comic book is stored in a JPEG or a TIFF file and a collection of such pages are encapsulated in a single archive. None of these file types can be opened in Windows by default. But with the right software installed, you can view comic books right from your computer.
Open with regular archive handling software
Although these files have odd looking extensions, they are compressed using standard file compression algorithms such as ZIP, RAR and ACE. See the table below for more information:
| Comic book archive Format | Actual compression used | Software |
| CBR | RAR | WinRAR [Download] |
| CBZ | ZIP | WinZip [Download] |
| CB7 | 7-ZIP | 7-Zip [Download] |
| CBT | TAR | WinZip [Download] |
| CBA | ACE | WinRAR [Download] |
Note that you can use any software that supports the actual compression to open a particular file type (not just the ones mentioned in ‘software to open’ column). Do not rename any of the archives to actual format. Just open the archive handling software, browse to .CBX file and choose to open it from within the program.
Open with special comic book reader software
In addition to the compression utilities mentioned above, there are comic book reader software which are specifically designed to open and view cbr, cbz and other file formats. Such software usually feature file type association, support for rotation, zoom, multi page view and other viewer enhancements, etc. Mentioned below are two of the most popular comic book reader software that are currently around.
