## Why They Matter  
Phil Katz's ZIP format revolutionized data handling by making file storage and transfer significantly more efficient. Before ZIP, large files were cumbersome to share or archive; his compression algorithm solved this problem universally. The format's integration into operating systems like Windows ensured its longevity, and it remains a default standard decades later. Without Katz's work, digital workflows—from software distribution to email attachments—would be far less practical. His legacy persists in countless applications relying on compressed data.
