Compare multiple documents protected by password Leave feedback

Note

This feature is available only for Word documents, PowerPoint, and Open Document presentations.

GroupDocs.Comparison allows you to compare more that two password-protected documents.

To compare several password-protected documents, follow these steps:

1. Instantiate the LoadOptions object. Specify source document password.
2. Instantiate the Comparer object. Specify the source document path or stream and the LoadOptions object created in the previous step.
3. Instantiate another LoadOptions object and specify target document password.
4. Call the add() method and specify the target document path or stream and the LoadOptions object created at previous step. Repeat steps 3-4 for every target document.
5. Call the compare() method.

The following code snippets shows how to compare several password-protected documents:

try (Comparer comparer = new Comparer(sourceFile, new LoadOptions("source-password"))) {
    comparer.add(targetFile1, new LoadOptions("target-password"));
    comparer.add(targetFile2, new LoadOptions("target-password"));
    comparer.add(targetFile3, new LoadOptions("target-password"));
    final Path resultPath = comparer.compare(resultFile);
}

try (Comparer comparer = new Comparer(sourceInputStream, new LoadOptions("source-password"))) {
    comparer.add(targetInputStream1, new LoadOptions("target-password"));
    comparer.add(targetInputStream2, new LoadOptions("target-password"));
    comparer.add(targetInputStream3, new LoadOptions("target-password"));
    final Path resultPath = comparer.compare(resultInputStream);
}
