 What are CBR, CBZ, CBT, RAR, ZIP and TAR files?

Computer files are generally compressed into archive data sets to save space and to organize information better. Common archives are RAR, ZIP and TAR. Comics have a “special” set of extensions to designate them as “comics”. CBR, CBZ and TAR files are comic archive files. A CBR file is the same as an RAR file, CBZ the same as a ZIP file, and CBT the same as a TAR file. The designations allow computers to associate comic reading software with files and allow other non-comic products to use the standard extensions.

The ZIP format takes one or more files and compresses them as one file, with a .zip file extension. The RAR format does the same (and has better compression sometimes).

The TAR format is found primarily on UNIX and Linux operating systems; it can be used on Windows and Mac platforms, although the ZIP format has become the most popular. (Most users are not familiar with .tar files.) The .tar file bundles files together, although without any compression. If a user wishes to compress them, they are advised to use gzip (which turns the compressed file into *.tar.gz ) .

Software programs for making/opening/viewing the contents of these .zip, .rar and .tar files can be found on the Internet.

How do I make my own CBR, CBZ and CBT files?

Place all comic scans into a folder and rename them in page order, eg. 001 002 003 and then archive the files using WinZip, WinRAR or other compression software. Now just rename them with the different extentions. Remember .zip files are .cbz; .rar files are .cbr; and .tar files are .cbt. (Viewers, like CDisplay, can read .all of these file formats, among other extensions, but the de facto standard has become .cbz and .cbr. We recommend you use these two formats.)

You can rename a *.cbz file to a *.cbr file and CDisplay will still view it, although it isn’t recommended. (This might be because WinRAR can read both .zip and .rar files.) Please stick to the original file format/extension name, especially if you’re distributing files via DC++ and/or Bit Torrent.

Also, if you are using WinRAR to rar images into an archive for CDisplay to view, you can just rename the extension from *.rar to *.cbr before you actually start the archiving process.

What’s so good about these digital comic viewing programs?

They’re a great way of viewing image archives, including various options which are optimised for digital comics!

Download the sequential image viewing utility.  Free!

The Windows Image Viewer ‘CDisplay’ was written to ease the viewing of images in JPEG, PNG and static GIF format.  This was partly down to the existing programs currently available being too general purpose and thus awkward to use when simply wanting to view images sequentially.

It was written using Borland C++ Builder 5.0 and has been tested under Windows 98, NT 4, 2000 and XP Tablet.

It is important to understand that this program has NO file write capabilities; files are left totally untouched.  A small amount of configuration data is written to the registry but apart from that the computer and its data is left untouched.

Features:

Loads JPEG, PNG and static GIF images which are automatically ordered and presented for viewing one at a time or two at a time.

The images may be in a zip, rar, ace or tar archive file - no need to decompress before reading.

Page through the images sequentially and scroll around pages with single key presses.

Automatic page sizing: none; fit to screen, fit to width of screen, fit to width of screen if oversized, display at specific height, or display two pages.  Resizing uses Lanczos interpolation for best picture quality.

Automatic colour balance and yellow reduction if desired.

No bloat caused by non-essential general purpose image processing features.

FREE.

    To Install:

Click on the link below to download setup.zip.  Unzip and run setup.exe.  An installer will start which will install and run the CDisplay Image Viewer.

Download version 1.8 NOW    

http://cdisplay.techknight.com/setup.zip

        Quick Start:

Run CDisplay.  CDisplay uses the entire display for images; there is no menu so right mouse click for a popup.  Choose load files.  Browse to the pages to read.  The whole directory will be pre-selected - just press go to read.  Or select a range of the files using left mouse click, shift left click and/or control left click (ie standard windows multiple selection keys) and press ok. Alternatively, select one ZIP or RAR file and press ok. The first page is displayed.  Use the space bar, page up, page down, home, end and the arrow keys to view the images.

See the ReadMe file or the help (F1 key) for a more detailed description of usage and configuration.

Files with a “.cbr” extension are basically a compressed set of JPG, PNG, or GIF images.
You can open them with the freeware program CDisplay (a comic book reader software).

Available here: http://www.geocities.com/davidayton/CDisplay.html

You can open .cbr files with WinRar (they are just .rar files with the file extension changed)
And .cbz files can be opened even with Windows XP’s default Compressed folder software (rename all .cbz files to .zip files and all .cbr files to .rar files)

Here is a list of free software that can be used to open .cbr files and .cbz files
