An early directory editor, [[Dired|DIRED]], was developed circa 1974 at the [[Stanford Artificial Intelligence Laboratory]] by [[Stan Kugell]].<ref>{{cite web |last=Kugell |first=Stanley G. |title=SAILDART/1974-08 |publisher=[[Stanford Artificial Intelligence Lab]] DART (Dump and Restore Technique) Archive |year=1974 |url=https://www.saildart.org/DIRED.SGK%5BUP,DOC%5D1 |access-date=2014-02-19 |url-status=live |archive-url=https://web.archive.org/web/20150903224616/http://www.saildart.org/DIRED.SGK%5BUP%2CDOC%5D1 |archive-date=2015-09-03 }}</ref><ref>[https://www.saildart.org/PHONE.LST%5BP,DOC%5D23 SAILDART Username key for above] {{webarchive|url=https://web.archive.org/web/20150903224616/http://www.saildart.org/PHONE.LST%5BP%2CDOC%5D23 |date=2015-09-03 }}</ref>

A directory editor was written for [[EXEC 8]] at the University of Maryland, and was available to other users at that time. The term was used by other developers, including [[Jay Lepreau]], who wrote the '''dired''' program in 1980,<ref>{{cite web|url=http://www.ibiblio.org/pub/Linux/utils/file/managers/dired305.lsm |title=Abstract for dired 3.05}}</ref> which ran on [[BSD]]. This was in turn inspired by an older program with the same name running on [[TOPS-20]]. '''Dired''' inspired other programs, including [[dired]], the editor script (for [[emacs]] and similar editors), and '''ded'''.
