No-Hassle CB7 File Support with FileMagic

A .CB7 file is a comic container built on top of 7-Zip, containing page images and optional metadata arranged in filename order so readers can present them like a book; CB7 exists for convenience, though support varies across devices, and converting to CBZ by extracting then re-zipping usually improves compatibility, with the archive itself opening like a standard 7z that should contain only images.

The “reading order” matters because an archive can’t automatically determine which page comes first—your reader app simply sorts filenames—so zero-padded numbers (`001`, `002`, `010`) prevent alphabetical mistakes like putting `10` before `2`; in essence, a CB7 isn’t a secret format but just a folder of image pages compressed with 7z and labeled `.cb7` so comic apps treat it as a book, making digital comics easier to share and manage without messy loose files, while apps provide smooth paging, zooming, library organization, and support for metadata like `ComicInfo.xml`, with the archive keeping pages together, optionally password-protected, and offering modest compression savings.

Inside a .CB7 file you’ll almost always see page images stored in order, named to preserve reading order and sometimes split by chapter folders, often including a cover and metadata (`ComicInfo.xml`), with occasional benign desktop clutter, but anything like `.exe` should raise alarms; to open it, use a comic reader that supports archives or simply extract it as a 7z file via 7-Zip/Keka/p7zip.

A quick way to check if a .CB7 file is safe is to open it using 7-Zip and confirm that it resembles a normal comic archive, which means mostly JPG/PNG files named in order and maybe a `cover.jpg` or `ComicInfo.xml`; if instead you find executables or scripts like `.exe`, `.bat`, `.ps1`, `.js`, or any non-image clutter, that’s a strong warning sign, and real comics typically show consistent file sizes, with any 7-Zip read errors suggesting corruption or an invalid file.
