Convert I04 to ISZ

Understanding i04 and isz file formats

i04 files are typically split parts of disc image files, often created by disc imaging software like Alcohol 120%. These files are not standalone images but segments of a larger image, usually accompanied by other parts such as .i00, .i01, and a main .mds file that contains metadata about the disc structure.

isz files are compressed disc image files developed by EZB Systems for their UltraISO software. The ISZ format is similar to ISO but supports compression and optional encryption, making it more efficient for storage and transfer.

How to convert i04 to isz

Since i04 is not a complete image but a part of a multi-part set, you must first reconstruct the full disc image using all the split files and the associated .mds file. Once you have the complete image, you can convert it to the isz format.

Step-by-step conversion process

1. Reassemble the image: Ensure you have all parts (.i00, .i01, .i02, .i03, .i04, etc.) and the .mds file in the same folder.
2. Mount or open the image: Use Alcohol 120% or DAEMON Tools to mount the .mds file, which will automatically use all the split parts.
3. Create a new ISO: With the image mounted, use UltraISO to create a new ISO file from the virtual drive.
4. Convert to ISZ: In UltraISO, open the newly created ISO file, then go to File → Save As and select ISZ as the output format.

Recommended software for conversion

• UltraISO – Best for converting ISO to ISZ and supports a wide range of disc image formats.
• Alcohol 120% – Essential for handling and mounting split image files like i04 and .mds sets.
• DAEMON Tools – Alternative for mounting split disc images.

Summary

To convert i04 (as part of a split disc image) to isz, you must first reconstruct the full image using all split files and the .mds descriptor. Then, use UltraISO to convert the complete image to the ISZ format for efficient storage and transfer.
