CHDman Batch

A portable, menu-driven interface for chdman — create, extract, verify and inspect CHD (Compressed Hunks of Data) files without touching a command line.

No installer. No setup. Extract the archive, run the script for your platform, and you're done.

---

Features

• Create CHD files from CD images (.cue, .gdi) or DVD images (.iso) — single file or entire folder trees
• Extract CHD files back to CUE+BIN, GDI, or ISO
• Verify the integrity of an existing CHD file
• Inspect detailed metadata of a CHD file
• Compress raw hard disk images into CHD format
• Batch mode: recursively scans a folder and processes every matching file
• Available in English, French, German, Spanish, Japanese, and Chinese

Getting started

1. Download the latest release for your platform from the Releases page

3. Run the script for your platform:
