📌The central directory's strategic location near the archive's end simplifies updates. This allows users to add or remove files easily without scanning the zip file using the central directory information. Each zip archive file has a "local file header" with important information, including file size, name, and more.

📌Verifying a zip file's integrity using the unzip command entails checking the "end of central directory record" with a specified signature. This signature is required for extraction, providing a strong validation method.
