The File Field Download module provides a simple yet powerful solution for Drupal websites that need to offer multiple files as a single download.

It enables site administrators to create a download link that automatically compresses any files attached to a node into a single ZIP archive, streamlining the file download process for end users.

This module is perfect for content managers who need to distribute document collections, media packages, or any group of related files efficiently.

Features

• Creates a custom "Download Link" field type that can be added to any entity.
• Compresses multiple files from specified file fields into a single ZIP archive.
• Allows administrators to select which file fields should be included in the ZIP download.
• Customizable download link label to improve user experience.
• Supports customization of the downloaded ZIP filename.
• Works seamlessly with existing file fields in your content types.
• Integrates with Drupal's entity system, making it compatible with any entity that uses file fields.
• Minimizes server load by generating ZIP files on-demand.

After installing the Download module, follow these steps to set it up:

1. Navigate to the "Structure" section in your Drupal admin menu.
