A CBT file uses TAR under the hood despite the .cbt extension, typically filled with numbered JPG/PNG/WebP pages plus possible metadata, and readers sort images alphabetically to display them; TAR’s lack of compression often results in bigger CBT files, and tools like 7-Zip can open them directly, while suspicious file types inside should be avoided, and converting to CBZ fixes most compatibility issues.

To open a CBT file, launching it in a comic reader is usually the ideal method, because the app handles page sorting and navigation for you; for manual access, extract the CBT with 7-Zip or rename it `.tar`, then inspect the images, reorganize numbering, or create a CBZ, and rely on archive tools to detect mislabeled or corrupted files while watching for unsafe executable entries.

Even the contents of a CBT file may change which workflow is recommended, 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 mostly a matter of reorganizing the archive, where you extract the CBT, check page numbering, zip the contents back so images aren’t buried in extra folders, rename to `.cbz`, and resolve Windows’ open errors by telling it which comic reader to use.

If you don’t want a comic reader and just need to extract images, right-clicking and using 7-Zip’s Open archive/Extract is generally enough, with renaming `.
