The file system was developed with a write-once CD-ROM simulator and was used to master one of the first CD-ROMs in 1986. CDFS was never sold, but its [[source code]] was published on the [[Internet]] and the CD-ROMs were distributed to Media Lab sponsors. The file system wasis the basis of WOFS (Write Once-once File System),<ref>{{cite article|title=Designing a Write-Onceonce File System|journal=Dr. Dobb's Journal|author=Simson L.
