About the formats
TAR archive
TAR (tape archive) bundles many files into a single uncompressed stream, preserving Unix permissions and structure. It is the backbone of Linux and macOS packaging, usually paired with gzip or bzip2 compression.
Strengths
- Preserves Unix permissions and symlinks
- Universal on Linux and macOS
- Ideal base for compressed tarballs
Limitations
- No compression on its own
- Not native to Windows
- No random access to members
Best for: Bundling files on Linux and macOS, ready to be compressed as a .tar.gz or .tar.bz2.
7z archive
7z is the native format of 7-Zip, using LZMA compression to squeeze files far smaller than ZIP. It supports strong AES-256 encryption and solid archives, at the cost of needing 7-Zip-compatible software.
Strengths
- Excellent compression ratio
- Strong AES-256 encryption
- Handles very large archives
Limitations
- Needs 7-Zip-compatible software to open
- Slower to compress
- Less universal than ZIP
Best for: Packing large collections as tightly as possible when recipients can use 7-Zip.
