TAR.7Z (T7Z) Dönüştürücü

TAR.7Z is a compound archive format that combines the TAR container with 7-Zip's LZMA/LZMA2 compression. The TAR layer bundles multiple files into a single stream preserving Unix metadata (permissions, ownership, symlinks), while the outer 7Z compression applies LZMA or LZMA2 to the entire stream. This combination leverages LZMA's superior compression ratios — typically 30-70% better than gzip — making TAR.7Z one of the most space-efficient archive formats for Unix-style backups and software distribution. The solid-stream approach means compression can exploit redundancy across all archived files rather than compressing each file independently. One advantage is maximum compression density: the TAR.7Z combination often produces the smallest archives among common Unix archive+compression pairings. Broad tool support is another strength — tar and 7-Zip are available on all major platforms, and many modern tar implementations can create and extract TAR.7Z archives directly with the appropriate flag. The format is popular for distributing large source code trees and backup archives where minimizing transfer size justifies the additional compression time.
