Compact Disc File System

The Compact Disc File System was a file system for read-only and write-once CDROMs developed by Simson Garfinkel and J. Spencer Love at the MIT Media Lab between 1985 and 1986. The file system provided for the creation, modification, renaming and deletion of files and directories on a write-once media. The file system was developed with a write-once CDROM simulator and was used to master one of the first CDROMs in 1986. CDFS was never sold, but its source code was published on the Internet and the CDROMs were distributed to Media Lab sponsors. The file system was the basis of WOFS (Write Once File System), sold by N/Hance systems in 1989.
