DEB is the Debian/Ubuntu package format: an ar archive whose members are control metadata plus data.tar.* holding the actual payload.
Typical use: Extract DEB payloads to inspect scripts, binaries and configs without installing.
About the DEB format
A .deb file is literally an ar archive (the Unix librarian format from 1971) containing three members: debian-binary, control.tar.* and data.tar.* — the last one holds every file the package installs. That transparency is why .deb extraction is the standard way to audit what a package will do to your system.
7-Zip parses the ar container and unpacks the inner tar automatically, so a browser can list and repackage the payload without ever touching a Linux shell.
Strengths
- ✓ Transparent, auditable package structure
- ✓ Standard across Debian, Ubuntu and derivatives
- ✓ Inner tar is trivially repackaged
Limitations
- ✗ Meaningless outside dpkg-based systems
- ✗ data.tar may use xz/zst compression variants
- ✗ No cross-platform installer equivalent
- Structure
- ar archive → control.tar + data.tar
- Types / schema
- Binary container, nested compression
- Compatibility
- dpkg, 7-Zip, ar tools
- Best for
- Debian-family software distribution
