Windows is not be able to install or run Mac software. Even though TransMac can open and extract files from a dmg image, only certain data files (image, video, text, html, sound, etc.) will be usable on a PC. While this format is generally exclusive to the Mac, our software TransMac can create, open, compress, decompress, split and burn dmg files on a Windows PC (APFS dmg read-only support starting with version 12.1). Since internal compression is supported, this format is sometimes used instead of general compression archive formats like Zip or Stuffit (.sit). Dmg files are often used for Mac software installation packages and general data exchange. Compressed dmg files are generally read-only. The dmg format includes options such as various volume types ( APFS or HFS+), compression options, encryption (password protection) and file spanning (segmenting). Changes to the volume change the dmg file instead of an actual disk drive. This mounted volume appears to the Mac as any other disk drive volume. When a dmg file is opened on a Mac, a disk volume icon will appear on the desktop as if an external drive was attached. This type of file can contain one or more file system volumes. dmg extension are a type of Macintosh OS X disk image.
