===Other file systems===
* The Prospero File System is a file system based on the Virtual System Model.<ref>{{cite book|url=http://citeseer.ist.psu.edu/viewdoc/summary?doi=10.1.1.132.7982|title=The Prospero File System: A Global File System Based on the Virtual System Model|year=1992}}</ref> The system was created by B. Clifford Neuman of the Information Sciences Institute at the University of Southern California.
* [[Flex machine#RSRE FLEX Computer System|RSRE FLEX file system]] - written in [[ALGOL 68]]
* The file system of the [[Michigan Terminal System]] (MTS) is interesting because: (i) it provides "line files" where record lengths and line numbers are associated as metadata with each record in the file, lines can be added, replaced, updated with the same or different length records, and deleted anywhere in the file without the need to read and rewrite the entire file; (ii) using program keys files may be shared or permitted to commands and programs in addition to users and groups; and (iii) there is a comprehensive file locking mechanism that protects both the file's data and its metadata.<ref>{{cite journal|url=https://ieeexplore.ieee.org/document/1451786|title=A file system for a general-purpose time-sharing environment|first=G.
