Batch ISO to XISO Converter streamlines the process of converting standard Xbox and Xbox 360 ISOs into the optimized, trimmed XISO format. Built with a flexible multi-engine architecture, the tool combines a native C# XDVDFS engine with robust external tool integration (extract-xiso and xdvdfs), delivering superior performance and modern features like real-time disk write monitoring.
Whether you're managing a large collection of Xbox game backups or verifying the integrity of your dumps, this application provides a user-friendly interface with powerful batch processing capabilities.
- Multi-Engine Support: Choose between the native C# XDVDFS engine,
extract-xiso.exe, orxdvdfs.exefor conversion - Smart Trimming: Rebuilds ISOs into XISO format, removing unnecessary system padding and saving gigabytes of storage
- Archive Support: Process
.zip,.7z, and.rarfiles directly with high-performance extraction via SharpCompress - CUE/BIN Support: Integrated
bchunksupport for converting classic disc images to ISO format - System Update Removal: Option to skip the
$SystemUpdatefolder for additional space savings (supported by native engine and extract-xiso)
- Structural Validation: Deep traversal of the XDVDFS file tree to ensure filesystem validity
- Deep Surface Scan: Optional sequential sector reading to detect physical data corruption or bad sectors
- Batch Organization: Automatically organize "Passed" or "Failed" images into dedicated subfolders
- Native Browsing: Open any Xbox ISO to browse files and directories without extraction
- Metadata View: View file sizes, attributes, and directory structures directly in the UI
- Double-Click to Open: Open files directly from the ISO with their default associated applications
- Drag & Drop Extraction: Drag files out of the explorer to extract them to any folder (Windows Explorer, Desktop, etc.)
- Real-time Statistics: Track success/fail counts, elapsed time, and processed files
- Disk Monitor: Live monitoring of write speeds and drive activity to identify hardware bottlenecks
- Cloud-Aware: Automatic detection and handling of cloud-stored files (e.g., OneDrive)
- Operating System: Windows 10 (version 1809) or later / Windows 11
- Runtime: .NET 10.0 Desktop Runtime
- Architecture: x64 (64-bit) required
- Download the latest release from the Releases page
- Extract the ZIP file to your desired location
- Run
BatchConvertIsoToXiso.exe
No installation required – the application is fully portable.
- Launch the application
- Click "Select Input Folder" and choose the directory containing your ISO files
- Click "Select Output Folder" to specify where converted files will be saved
- Configure options:
- Remove System Update: Skip
$SystemUpdatefolder to save space - Replace Originals: Replace input files with converted versions
- Test After Conversion: Automatically verify converted ISOs
- Conversion Method: Select between extract-xiso, xdvdfs, or Native Logic
- Remove System Update: Skip
- Click "Convert" to start the batch process
- Switch to the "Test ISO" tab
- Select your input folder containing ISO files
- Enable "Move Passed Files" and/or "Move Failed Files" to organize results
- Click "Test ISOs" to begin validation
- Switch to the "XISO Explorer" tab
- Click "Open ISO" and select an Xbox ISO file
- Browse the file tree to view contents without extraction
- Open Files: Double-click any file to open it with its default application
- Extract Files: Drag and drop files from the explorer to Windows Explorer, Desktop, or any folder to extract them

The application follows modern software engineering principles with a clean, maintainable architecture based on Dependency Injection and Service-Oriented Design.
Utilizes Microsoft.Extensions.DependencyInjection for comprehensive service management. All core logic is decoupled from the UI, enabling easier testing and modular updates.
