What is CDFS File & How to Open CDFS Files?

Before talking about CDFS, we'll introduce the development of CD first. James Russell invented the original Compact Disc (CD), and the design was eventually finalized when Sony and Phillips created the ‘Red Book’ standard sometime around 1980. However, the CD officially made its way to the public sometime after 1983, after Sony which back then was also an electronics giant released the Sony CPD-101 CD player. While the CD offered around 20 albums at launch, it grew exponentially over the years, and by the time the world got to 1991, it had overtaken the cassette by a margin. Originally, CD casings were unnecessarily long and bigger than necessary measuring at 6 by 12 inches, but this design was an effort to make it easier to flip through discs on shelving units designed for LPs. The so-called longbox packaging was responsible for creating an estimated 18.5 million pounds of extra trash each year, and due to pressure from environmentalists and the public, the smaller plastic versions that we know today were developed.

With the release of the DVD discs which offered more storage space, and with the release of the original iPod and iTunes in 2001, the Compact Disc began to see its decline. Today, the CD is just as good as obsolete, although Blu-ray and DVD players still support them. The CDFS file system format is associated with Compact Discs, and the CDFS can contain either Red Book Audio, or White Book Video. We will discuss "what are cdfs" and show you the best CDFS player.

Part 1: What is CDFS format?

CDFS stands for Compact Disc File System, and it was first introduced between 1985 and 1986 on Linux and it exports all tracks and boot images on a CD as normal files. For Windows computers, it is basically the driver for CD-ROM players. CDFS can contain either Red Book Audio, or White Book Video. When it was introduced on 21 August 1999, it was considered the most advanced technology in the technology industry, because prior to its introduction, there was no medium for people to store their files for long term purposes but that was all changed with the release of CDFS.


1. Brief History about CDFS

Between 1985 and 86, Simon Garfinkel and J. Spenser developed CDFS at the MIT Media Lab, from the write-once CD-ROM simulator. CDFS was developed to store data (images, videos, audios, etc.,) on read-only and write-once media. In order to do the world a favor, the developers of this file system format published the source code on the internet and it never got sold.

2. CDFS Applications

Apart from containing Red Book Audio or White Book Video, or being the driver for CD-ROM players, the CDFS file system has the following applications:

  • 1. CDFS creates pathways in which the system first sets up the root directory. Afterward, it creates all subsequent folders for it.
  • 2. CDFS is not only limited to a single operating system, (it was first introduced on Linux between 1985 and 1986), but it also works with Windows and macOS systems. That means when you burn a disc from macOS and Windows, it is also utilizing this file system.
  • 3. It provides a wide range of services for all users. For instance, any user can create new files or folders which are added to the main root file of the system.
  • 4. It is useful for burning discs that can be exchanged between different devices (on Linux, Windows or macOS systems). What that means is the files you burn from either system can directly work on the other system.
  • 5. It can also help to save disc pictures using the proper system standards.

CDFS Windows 10 errors have been reportedly rampant, with some users experiencing CDFS File System errors. However, this issue can be easily fixed through updating drivers, safe mode and through the Windows automatic repairs. If you wish to view a DVD with a CDFS format, you can refer to the guide below on how to do so.

Part 2: How to open CDFS files? - Best CDFS player

The CDFS stands for CD File System, and it is a file extension for any virtual file system used with Linux. CDFS can contain either Red Book Audio, or White Book Video. From this basic description about what is CDFS, you can probably tell that it is one of the rarer container format that stores audios and videos. As such, it is natural that most modern media playback software cannot support this file format, except for a few professional CDFS players like Leawo Blu-ray Player. The support for CDFS files was added with the release of Leawo Blu-ray Player for Win It can easily support CDFS files (both audio and video), because it was built to support over 180 video and audio formats which include AVI, ASF, MPEG, WPL, FLV, MKV/MKA, QuickTime, AAC, VC-1, OGG, OGM etc.

As the name suggests, Leawo Blu-ray Player is qualified to play Blu-ray/DVD discs, folders and associated file formats with ease. It is notable that this versatile program could play Blu-ray/DVD content with region protection directly (like playing region A Blu-ray disc in Europe ) since it owns a built-in decrypter inside.
