How to ZIP a Folder in C#

This quick article explains how to zip a folder in C#. It provides detailed steps and a code sample to assist in creating a ZIP file for a folder and its contents. This solution does not require installing any third-party tools.

Benefits of Zipping Folders

  1. Space Efficiency:
    • Reduces storage space by compressing files.
  2. Organized File Management:
    • Combines multiple files into a single archive for easier distribution and management.
  3. Faster Transfers:
    • Smaller file sizes lead to quicker upload and download times.

Prerequisites: Preparing the Environment

  1. Set up Visual Studio or any compatible .NET IDE.
  2. Install the Aspose.ZIP library via NuGet Package Manager.

Step-by-Step Guide to ZIP a Folder

Step 1: Install Aspose.ZIP

Add the Aspose.ZIP library to your project.

Install-Package Aspose.ZIP

Step 2: Create a FileStream Object

Instantiate a FileStream object for the output ZIP file.

using System.IO;
var zippedFolder = File.Open("AnimationImages.zip", FileMode.Create);

Step 3: Create a ZIP Archive Object

Create an instance of the Archive class to handle ZIP operations.

using (Archive archiveFile = new Archive())
{
    // Further processing follows here
}

Step 4: Create Entries in the Archive

Add all files and folders from the target directory recursively.

archiveFile.CreateEntries("AnimationImages");

Step 5: Save the ZIP File

Once the entries are created, save the archive to disk.

archiveFile.Save(zippedFolder);

Complete Code Example to ZIP a Folder

Here’s the complete C# example demonstrating how to zip a folder:

// Create a file stream object for the output zip file
using (FileStream zippedFolder = File.Open("AnimationImages.zip", FileMode.Create))
{
    // Create a Zip archive file class object
    using (Archive archiveFile = new Archive())
    {
        // Add all the files and folders recursively
        archiveFile.CreateEntries("AnimationImages");

        // Save the output ZIP file
        archiveFile.Save(zippedFolder);
    }
}

Additional Information

  • You may provide a DirectoryInfo class object as the source of the files for the output ZIP file.
  • You can also include flags to control whether to include the root folder in the output ZIP.
