A CBT file implements comic packaging via the TAR format, filled with page images sorted alphabetically by readers, sometimes including metadata, and because TAR doesn’t compress, CBT files can be larger than CBZ/CB7; they open easily in comic apps or via extraction tools, and any executable/script inside warrants suspicion, with CBZ often used when CBT support is limited.

To open a CBT file, the easiest option is using a comic reader, since readers treat the archive like a book and automatically handle page order, zoom, and navigation; on Windows you can often just double-click and choose a reader, but if you prefer the raw images you can open the CBT as a TAR-style archive with 7-Zip or by renaming it to `.tar`, then view or reorganize the extracted pages, convert them into a CBZ (ZIP→.cbz) for better compatibility, or troubleshoot mislabeled or corrupted files by letting 7-Zip auto-detect the format while steering clear of suspicious executables.

Even the contents of a CBT file can affect whether you should rename, reorganize, or convert, because sloppy numbering (`1.jpg, 2.jpg, 10.jpg`) can force page-order fixes, folder structures may confuse certain readers, and unusual non-image files call for safety inspection; tell me your device, app, and goal so I can give a tailored workflow, but in general you either open CBTs in a comic reader for smooth viewing or treat them as TAR archives for extraction by renaming to `.tar` or using 7-Zip, then correcting filenames, reorganizing folders, or converting the result into a CBZ for maximum compatibility.

Converting a CBT to CBZ is essentially a format swap from TAR to ZIP, involving unpacking the CBT, ensuring filenames sort properly, creating a ZIP with images placed at the top level, renaming it to `.cbz`, and fixing Windows’ "can’t open" message by setting a comic reader as the default handler.

If you don’t want a comic reader and just need to extract images, 7-Zip can pull the pages out immediately, with renaming `.cbt` → `.
