Understanding TAR and 7Z Formats

Learn about the source and target file formats to understand what happens during conversion.

Source Format

Tar Archive

application/x-tar

TAR (Tape Archive) is a Unix archive format that bundles multiple files and directories into a single file while preserving file permissions, ownership, timestamps, and symbolic links. TAR itself performs no compression; it is purely an archival format. TAR is almost always used in combination with a compression tool like gzip, bzip2, or xz to create compressed archives.

Advantages

  • Preserves Unix file permissions, ownership, symbolic links, and timestamps
  • Standard archival format on all Unix and Linux systems
  • Extremely simple and reliable format with decades of proven use

Limitations

  • No built-in compression; must be combined with a separate compression tool
  • No random access to individual files without reading the entire archive
  • No built-in encryption or password protection

Common Uses

  • Linux and Unix software distribution and source code packaging
  • System backup and file archival on Unix platforms
  • Bundling files before applying compression with gzip, bzip2, or xz

Target Format

7-Zip Archive

application/x-7z-compressed

7z is an archive format developed by Igor Pavlov for the 7-Zip archiver, using LZMA and LZMA2 compression algorithms by default. It supports multiple compression methods, solid compression (compressing multiple files as a single data stream), AES-256 encryption, and very large file sizes. 7z typically achieves 30-70% better compression than ZIP for similar content.

Advantages

  • Excellent compression ratios, typically 30-70% better than ZIP
  • Strong AES-256 encryption for archive and filename protection
  • Solid compression mode further improves ratios for similar files

Limitations

  • Not natively supported by operating systems; requires 7-Zip or compatible software
  • Slow compression speed compared to ZIP, especially at high settings
  • No preservation of Unix file permissions in standard implementations

Common Uses

  • Maximum compression for large file distribution and archival
  • Encrypted file storage and secure file sharing
  • Software distribution where download size is critical
