Then use the program Split and Concat to join the files and make an ISO.

How to open:

Use any disk image working program to open files with i03 extension.

How to convert:

As far as we know, this .i03 file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
