ByWhat is a DMG File and why is it used?
DMG stands for Disk Image File. It is primarily used in the macOS (Apple Mac) operating system. A DMG file is a type of container that holds software, applications, installation files, or an entire virtual disk structure. When a Mac user downloads an app, it is often in DMG format.
However, when this file is transferred to a Windows computer, problems arise because Windows does not support DMG files by default.
Why DMG Files Don’t Open in Windows
The Windows operating system works on NTFS and FAT-based systems, while DMG files are based on macOS’s HFS+ or APFS file system. This is why double-clicking a DMG file on Windows does not open it.
