Content Mode

  • Selects volume
  • Extracts files
  • Packages into 7Z with folder structure

Preserve Image Mode

  • Converts DMG to raw image/ISO stream if possible (depending on the platform)
  • Puts the resulting image.iso or image.img file into 7Z

Note: 7-Zip lists DMG in the “unpack” list; however, in practice, there may be failure scenarios depending on the FS/layer combinations within the DMG.

When to choose DMG to 7Z?

  • If you want to pull the archive standard to 7Z
  • If you are targeting a “single file high ratio”
  • If you want stronger archive management than ZIP
