What is a ZIP Archive?
A ZIP archive is a compressed file container format that bundles one or more files and directories into a single file with reduced size, widely used for transferring, distributing, and backing up website files.
How Does Zip Archive Work?
ZIP compression works by identifying and eliminating redundant data patterns within files, reducing the overall size without losing any information (lossless compression). A single ZIP archive can contain an entire directory structure with hundreds of files, preserving folder hierarchy and file metadata. The format is universally supported across operating systems and can be created and extracted using built-in tools on Windows, macOS, and Linux.
In web hosting, ZIP archives are commonly used for uploading website files to a server, downloading backups, and distributing themes or plugins. Most hosting control panels like cPanel and Plesk include file managers that can create and extract ZIP files directly on the server, making it much faster to upload a single archive than transferring thousands of individual files via FTP. ZIP archives can also be password-protected for an additional layer of security during file transfers.
