This conversion was mostly used to convert disk images of floppy diskettes (.imz) to Universal Disk Format (.udf), something that can be done with programs such as WinImage or similar. It is likely that other disk image handling utilities may be capable of imz to udf as well, although the support for floppy disk is slowly phasing out.

The table with program actions contains information about what each program is capable of doing with their files. This may be a good pointer for further searches for certain file conversions and help you find the converter you are looking for if our search result is insufficient for you. However, it is far from perfect and may sometimes show results which are not really usable because of the nature of the software handles the files. So a conversion that appears as possible, just because of matched actions, may in fact not be possible.
