What to expect
- The files are re-compressed under bzip2; contents are unchanged, only the compression format differs.
- bzip2 compresses a single stream, so multiple files are usually wrapped with tar first (
.tar.bz2). - As with any archive, only extract
.bz2/.tar.bz2from sources you trust.
Frequently asked questions
What actually happens when I convert ZIP to BZ2?
A ZIP is a multi-file container, while bzip2 compresses a single stream, so the data is re-compressed under bzip2 rather than kept in ZIP form. The files themselves are not altered; only the compression wrapper changes.
Can a BZ2 hold all the files that were in the ZIP?
Plain
.bz2 compresses one file or stream, so multiple files are normally first bundled with tar, giving a .tar.bz2. That is the standard way bzip2 carries more than one file.What opens a BZ2 file?
On Windows, 7-Zip or PeaZip; on macOS, Archive Utility handles it by double-click; on Linux,
bunzip2 file.bz2 or tar -xjf file.tar.bz2. All are free and widely available.Will this save space?
bzip2 often compresses text and similar data more tightly than ZIP's DEFLATE, though it is typically slower. Already-compressed content (media, or the ZIP's own compressed entries) will not shrink much further.
