Merge ZIP Java

Merging ZIP files can simplify the management of multiple compressed archives by combining them into one. This is especially useful in scenarios like combining backups, log files, or application assets. In this post, we’ll learn how to merge ZIP files using Java.

Why Merge ZIP Files in Java?

Merging ZIP files is often necessary when dealing with large amounts of data split across multiple archives. Some key reasons to merge ZIP files include:

  • Efficiency: Combines multiple archives into one file for easier access and management.
  • Convenience: Reduces clutter by storing related files together in a single ZIP.
  • Portability: Distributes a single compressed file instead of multiple ZIP archives.

Merge ZIP Files - Java API Configuration

For merging ZIP files in your environment, you have to configure Conholdate.Total for Java on your end. You can download the JAR file or paste the following Maven configurations in the pom.xml file:

<dependency>
<groupId>com.conholdate</groupId>
<artifactId>conholdate-total</artifactId>
<version>24.6</version>

  • Join additional ZIP files: The join() method allows you to add other ZIP files to the merge process.
  • Save the result: Finally, the save() method merges the added ZIP files and outputs a single, merged ZIP file.
