Instead of converting files one by one via a command prompt, you can use a script to handle your entire folder automatically. Open on your computer. Paste the following command script into the blank document: Convert Zip To Chd
CHD (Compressed Hunks of Data) is a compression format built specifically for retro games. It keeps games compressed while allowing emulators to read the data instantly.
Because CHD compression is entirely lossless, you can always convert a CHD back into its original raw .bin / .cue format later using the command chdman extractcd if you ever need to modify the game files. Automates the process for large libraries

You will extract the ZIP file first, leaving you with the raw disc files. You can safely delete the extracted
The definitive PlayStation 2 emulator (supports CHD natively in modern nightly builds).
| Feature | ZIP | CHD | | :--- | :--- | :--- | | | Generic Deflate | Hunk-level, sector-based | | Multi-track support | Requires multiple files (BIN/CUE) | Single-file container | | Audio compression | None (WAV inside ZIP is huge) | Lossless FLAC for CD audio | | Space savings | Moderate (20–30%) | High (40–60%+ for CD audio) | | Streaming | Must decompress entire archive | Seekable & streamable | | Metadata/Error corr. | No | Yes (checksums) |
Unlike standard compression formats like ZIP or RAR, emulators can read CHD files directly without needing to extract them into your computer's temporary memory first. This means you get the space savings of a compressed file with the instant loading speeds of an uncompressed image. Why Convert ZIP to CHD?
Converting files to CHD (Compressed Hunks of Data) is a standard space-saving technique for retro gaming emulators.
