What is a DMG file?

The DMG (Apple Disk Image) format is a proprietary disk image container developed by Apple Inc., functioning as a virtual volume that encapsulates file systems including HFS+ (Mac OS Extended) and APFS (Apple File System). Built on the Universal Disk Image Format (UDIF) specification, DMG archives support block-level compression algorithms such as zlib, bzip2, ADC (Apple Data Compression), and LZFSE, alongside optional 128-bit or 256-bit AES encryption. The file structure concludes with a trailer containing an XML property list (plist) and a Resource Fork, which define the partition map and include CRC-32 checksums for data integrity verification during the mounting process.

How to open a DMG file

On macOS, DMG files are handled natively by the Apple DiskImageMounter utility, which mounts the image as a virtual drive within Finder without requiring external software. Windows operating systems lack the kernel-level drivers to read HFS+ or APFS file systems; therefore, users must rely on third-party extraction utilities such as 7-Zip, PeaZip, or TransMac to access the contained data. In Linux environments, users typically employ the command-line tool dmg2img to convert the archive into a standard ISO format before mounting, or use p7zip for direct extraction.

What is a ZIP file?

The ZIP format is an archive file format capable of lossless data compression, originally created by Phil Katz of PKWARE. It utilizes a Central Directory structure to catalog files and supports various compression algorithms, most notably DEFLATE (RFC 1951). The format is standardized under ISO/IEC 21320-1:2015 as a document container file and serves as the base structure for modern file types like .docx and .jar.

How to open a ZIP file

The ZIP format enjoys universal native support across all major operating systems, including Windows (File Explorer), macOS (Archive Utility), and Linux. No third-party software is strictly required for basic extraction, though power users often employ tools like 7-Zip or WinRAR to access advanced features like AES-256 encryption or multi-volume spanning.
