| Description | The DMG (Disk Image) format is a proprietary disk image file format used primarily in macOS operating systems. It is commonly used for distributing software applications and operating system installations. DMG files contain a compressed archive of files and folders, often including application binaries, libraries, and resources. They can also include disk images, allowing users to mount them as virtual disks and access their contents without extracting them. DMG files may be encrypted or password-protected for added security. To access the contents of a DMG file, users typically double-click it to mount it as a virtual disk, then browse its contents using Finder or other file management tools. Additionally, DMG files can be converted to other formats or burned to physical media for distribution or backup purposes. |
| Technical details | An HTML file is a disk image containing the contents of a disk, such as a hard drive, optical disc, or USB drive. It can include files, folders, and filesystem metadata. |
