Stands for “Hierarchical File system”, HFS are the Apple Macintoshes record system used for the documents on floppy disks, CD ROM discs, and hard disk drives. It can also be found on read-only media such as CD-ROMs. HFS is also referred to as Mac OS Standard.
 

However, MFS had been optimized to be used on very small and slow media, namely floppy disks, so HFS was introduced to overcome some of the performance problems that arrived with the introduction of larger media, notably hard drives. The main concern was the time needed to display the contents of a folder. Under MFS all of the file and directory listing information was stored in a single file, which the system had to search to build a list of the files stored in a particular folder.
 

This worked well with a system with a few hundred kilobytes of storage and perhaps a hundred files, but as the systems grew into megabytes and thousands of files, the performance degraded rapidly. The hierarchical file system is used to create a directory that can expand as new files and folders are added to the disk.
