MISO-J is a file appending utility which is able to join multiple files in a single one. For example, 001.txt 002.txt 003.txt --> output.txt, or Converted multiple segment image files are groups of "xxx.mds, xxx.I00, xxx.I01, xxx.I02" or "xxx.mds, xxx.mdf, xxx.md0, xxx.md1" to ISO image.
The operation is easy, we just drag and drop these files (MDS, MDF, MD0, MD1...) into table view of MISO-J. And then, we can convert them for burning ISO image on Mac.
