This paper is a description of a filestore structure of a single-user operating system MICRODOS (see [Ranai, 1, 2]). A hybrid filestore structure of the random page map type (SOLO system see [Hansen, 5]) and the sequential chain linked type (OS6 system see [Stoy and Strachey, 3, 4]) was adopted for MICRODOS system.
