A hierarchical file system (HFS) data set is a data set that contains a POSIX-compliant hierarchical file system, which is a collection of files and directories organized in a hierarchical structure that can be accessed using z/OS® UNIX system services.

Most applications that use these access methods can access HFS files without reassembly or recompliation. The contents of HFS data sets are structured like a tree, based on a root directory with various subdirectories. The files within an HFS data set are identified by their path and file names.
