What is an MPG file?

The MPG file extension is functionally identical to the MPEG format, restricted historically to a three-letter filename in MS-DOS and early Windows environments (8.3 filename convention). It typically contains video and audio interleaved in an MPEG-1 or MPEG-2 Program Stream (PS) container. MPG files are standard for VCD (Video CD) and DVD-Video content, utilizing inter-frame compression to reduce file size while maintaining VHS-comparable or broadcast-quality resolution depending on the bitrate and standard version utilized.

How to open an MPG file

Due to its legacy status as a standard distribution format, MPG files open natively on almost all desktop and mobile platforms without external codecs. Windows Media Player, Apple QuickTime, and GNOME Videos handles MPG-1 and MPEG-2 streams automatically. If playback issues occur due to corrupted headers or proprietary data streams, VLC Media Player is the industry-standard fallback utility.

What is a FLAC file?

The Free Lossless Audio Codec (FLAC) is an open-source audio coding format developed by the Xiph.Org Foundation that compresses digital audio without any loss of data (bit-perfect preservation). It employs linear prediction and Rice coding (Golomb-Rice) rather than the perceptual psychoacoustic modeling used in MP3 or AAC. The format structure consists of the 'fLaC' stream marker, metadata blocks (Streaminfo, Vorbis comments for tags, Seekpoints), and audio frames, typically achieving compression ratios of 50-70% compared to raw PCM WAV files.

How to open a FLAC file

FLAC enjoys extensive native support on modern platforms, including Windows 10/11, Android, and macOS (starting with macOS High Sierra). For older systems or advanced playback control, software such as Foobar2000 (Windows) or Vox (macOS) is recommended. The VLC media player is a universal solution for all operating systems, handling FLAC streams and associated metadata seamlessly.
