Compact Disc File System
Encyclopedia
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.

Source code
In computer science, source code is text written using the format and syntax of the programming language that it is being written in. Such a language is specially designed to facilitate the work of computer programmers, who specify the actions to be performed by a computer mostly by writing source...
