Implementation Guide

Feature 1: Load OST File

Overview

Loading an OST file correctly is essential for a successful conversion. This section covers using specific load options tailored for email files like OST.

Step 1: Verify File Format and Apply Load Options

using System;
using GroupDocs.Conversion;
using GroupDocs.Conversion.Options.Load;

var sourceFilePath = @"YOUR_DOCUMENT_DIRECTORY/Sample.ost"; // Replace with your actual document directory path

// Check if the file format is OST and apply PersonalStorageLoadOptions
var loadContext = new LoadContext { SourceFormat = FileTypes.EmailFileType.Ost };
var options = loadContext.SourceFormat == FileTypes.EmailFileType.Ost 
    ? new PersonalStorageLoadOptions() 
    : null;

using (var converter = new Converter(sourceFilePath, () => options))
{
    // Proceed with conversion steps
}

Explanation: This code checks if the file is an OST type and applies PersonalStorageLoadOptions to handle specific email file characteristics.

Feature 2: Convert OST to PDF

Overview

Converting an OST file into a PDF format ensures compatibility across different platforms, making your data easily shareable. Follow these steps for conversion using GroupDocs.Conversion.

Step 1: Initialize Converter and Set Up Conversion Options

using System;
using System.IO;
using GroupDocs.Conversion;
using GroupDocs.Conversion.Options.Convert;

var outputFolder = @"YOUR_OUTPUT_DIRECTORY"; // Replace with your actual output directory path
var outputFileTemplate = Path.Combine(outputFolder, "ost-converted-{0}-to.pdf");

using (var converter = new Converter(sourceFilePath))
{
    var options = new PdfConvertOptions(); // Set up PDF conversion options
    int counter = 1; // Counter for naming multiple output files if necessary

    // Perform the conversion and save the result as a PDF file
    converter.Convert(
        (SaveContext saveContext) => 
            new FileStream(string.Format(outputFileTemplate, counter++), FileMode.Create),
        options
    );
}

Explanation: This code snippet initializes the Converter class with the source OST file and sets up PDF conversion options. The conversion process is executed, saving each resulting PDF to a specified output directory.

Troubleshooting Tips

  • Ensure your OST files are accessible and not corrupted.
