Convert ISZ to MDS

Understanding ISZ and MDS file formats

ISZ is a compressed disk image format developed by EZB Systems, commonly used by UltraISO. It is essentially a compressed and, optionally, encrypted version of the standard ISO image file, making it more space-efficient for storing CD/DVD images.

MDS (Media Descriptor File) is a format used to describe the layout of a CD or DVD image, often paired with an MDF file that contains the actual data. MDS files are commonly used by disc imaging software like Alcohol 120% and Daemon Tools, especially for images with multiple tracks or copy protection.

Why convert ISZ to MDS?

Converting from ISZ to MDS is useful if you need compatibility with software or hardware that does not support ISZ but works with MDS/MDF pairs. MDS/MDF is also preferred for images with complex structures, such as multi-track discs or those with copy protection.

How to convert ISZ to MDS

Direct conversion from ISZ to MDS is not natively supported by most software. The typical process involves two steps:

1. Decompress the ISZ file to ISO: Use UltraISO or a similar tool to convert the ISZ file back to a standard ISO image.
2. Convert ISO to MDS/MDF: Use Alcohol 120% or PowerISO to convert the ISO file to an MDS/MDF pair.

Recommended software for ISZ to MDS conversion

• UltraISO: Open your ISZ file and use File → Save As to export it as an ISO file.
• Alcohol 120%: Use Image Making Wizard to create an MDS/MDF image from the ISO file.
• PowerISO: Open the ISO file and use Tools → Convert to select MDS as the output format.

Step-by-step conversion process

1. Open your ISZ file in UltraISO.
2. Go to File → Save As and select ISO as the output format.
3. Open the resulting ISO file in Alcohol 120%.
4. Use the Image Making Wizard to save the image as MDS/MDF.

Conclusion

While there is no direct one-step ISZ to MDS converter, using UltraISO and Alcohol 120% or PowerISO in sequence provides a reliable solution. This ensures your disc images are compatible with a wider range of emulation and burning tools.
