Load and Merge MHTML Files

This section guides you through loading multiple MHTML files and merging them into a single document.

Overview

Combining MHTML files streamlines the process of handling web-based content, making it easier to share or archive. With GroupDocs.Merger, this task becomes effortless.

Step-by-Step Instructions

1. Define Output Directory

Specify where you want your merged file saved:

String outputFolder = "YOUR_OUTPUT_DIRECTORY";

2. Initialize Merger with the First MHTML File

Load the initial source file to begin merging:

Merger merger = new Merger("YOUR_DOCUMENT_DIRECTORY/SAMPLE_MHTML");

Explanation: Here, Merger is initialized with the path of your first MHTML document.

3. Add Additional MHTML Files

Add more files using the join method:

merger.join("YOUR_DOCUMENT_DIRECTORY/SAMPLE_MHTML_2");

Explanation: This step appends another MHTML file to the merger instance, preparing it for a unified output.

4. Save the Merged Result

Finally, save your merged document:

String outputFile = new File(outputFolder, "merged.mhtml").getPath();
merger.save(outputFile);

Explanation: The save method consolidates all added files into one specified by outputFile.
