Windows, Macintosh, Unix/Linux: today, they all support a hierarchical directory structure. The differences are in the details (mount points vs drive letters), but all use a hierarchical directory structure.
The accepted answer to question Is there a reason why MS-DOS didn't use more English words for commands? says DOS 2.0 added hierarchical directory structure, so I believe Unix had it before DOS.
But was the hierarchical directory structure invented for Unix? Or was there something before Unix that supported a similar hierarchical directory structure?

The first hierarchical system capable of supporting arbitrary directory structures was designed for Multics, which pre-dates Unix. It is described in A General-Purpose File System For Secondary Storage, although it should be noted that that paper is a design document and doesn’t quite reflect the file system actually implemented a few years later in Multics.
Earlier systems had hierarchical file systems, but not capable of storing arbitrary layouts; see for example the ERMA Mark I’s file system (1958). CTSS (1961) had the concept of directories to some extent, or at least separate storage within the same file system for different users and projects (Dennis M. Ritchie wrote that “a good case can be made that [Unix] is in essence a modern implementation of MIT’s CTSS systemâ€Â).
