A BZ file is generally a bzip2-compressed file, meaning it’s not a document format but a compressed package, usually seen as `.bz2` (with older `.bz` also existing), and it normally expands back into one original file—like `data.csv.

To open a BZ/BZ2 file the key step is learning whether a `.tar` is inside, because `.bz2/.bz` normally decompresses to one item whereas `.tar.bz2/.tbz2` produces a `.tar` that must then be unpacked; Windows users can extract with 7-Zip/WinRAR, macOS users with The Unarchiver/Keka, and Linux users with `bunzip2` or `tar -xjf`, and using an archiver quickly reveals whether the file holds many items or just one.

Under the hood, bzip2 makes files smaller by converting scattered repetition into compressible runs, allowing compact run-length and symbol encoding while keeping precise reversal instructions so the output restores perfectly; it often produces smaller results than gzip or common ZIP settings on logs and code but at higher CPU cost, fitting archival workflows, and it became a common Unix/Linux packaging choice for source distributions thanks to predictable behavior and solid compression without the extreme slowness of high-end xz modes.

ZIP and gzip solve different problems, with gzip known for speed and streaming in `.gz`/`.tar.gz` formats, and ZIP acting as a multi-file bundle common on Windows but offering variable compression; bzip2 combined with tar (`.tar.bz2`) delivers stronger, consistent compression and fits a Unix-centric niche where size efficiency is preferred over raw speed.

bzip2 exists to serve cases where storage efficiency outweighs performance, giving smaller results on logs, CSVs, or code but needing more CPU, making it ill-suited for real-time pipelines but valuable for long-term storage; ZIP’s ability to bundle files contrasts with bzip2’s single-stream compression, so tar provides the container step before bzip2 compresses it, and this combination is common in Unix/Linux distributions, backups, and log archives.

You’ll sometimes see `.bz` instead of `.bz2` because both mark the file as bzip2 data, though `.bz2` has become the widely accepted norm; early systems leaned on the shorter `.bz` for convenience, but `.bz2` grew popular as a more explicit, cross-platform-friendly naming convention, and in practice extraction tools don’t care which extension is used as long as the header is valid bzip2, so older scripts may still output `.bz` while newer packaging favors `.bz2`, and both open fine in standard archivers or via `bunzip2` on Linux.
