Introduced with DOS version 2 is support for hard drives, sometimes called fixed disks. (the latter name come from the fact that they could not be removed, like a floppy could).
As we learned earlier, FDISK was needed before formatting. After a hard disk was formatted and contained an OS (operating system), a method of creating virtual floppies on the fixed disk was needed.
These virtual floppies are called sub directories or folders.
There are several reasons for this need. One need is a human one. That is to give order to the capability of the fact that thousands of files could be stored.
The second reason was a technical issue. The indexing system that controlled where the magnetic bits were that told DOS what made up a file, was limited to 512 file entries!
