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 RAR file?
RAR (Roshal Archive) is a proprietary archive file format developed by Eugene Roshal that supports data compression, error recovery, and file spanning. It utilizes a variation of the LZSS algorithm with a sliding window size of up to 4 MB (in RAR4) or 1 GB (in RAR5), combined with Huffman coding. Key technical features include support for AES-256 encryption, BLAKE2sp hash algorithms for file integrity, and specialized recovery records that allow for the reconstruction of damaged data. The format structure supports solid archiving, where multiple files are treated as a single continuous data stream to improve compression ratios.
How to open a RAR file
Due to the proprietary nature of the RAR licensing, creating RAR files requires licensed software (WinRAR), though extraction is supported by various free tools. Windows users typically use WinRAR or 7-Zip to extract contents. macOS users can utilize The Unarchiver or Keka. On Linux, the non-free unrar package or the open-source 7z (p7zip-full) package provides extraction capabilities via the command line.
