Its primary role is to organize and store files on a Macintosh hard disk. HFS –On a Macintosh computer, HFS (Hierarchical file system) is the file system that is used to create a directory when a hard disk is formatted.
It also helps to extend the life of a hard drive by reducing hard drive wear and tear.

It is also commonly found in devices such as digital cameras, flash memory, and other portable devices, where it is used to store file information. It helps Microsoft operating systems manage files on hard disks and other physical media devices.
File Allocation Table (FAT) was first introduced in 1977. Because files are commonly organized in a hierarchy, the file system allows you to browse the files in the current directory.įollowing are some of the examples of File Systems:-įAT – FAT is a file system designed specifically for hard drives.

Although Windows supports a variety of file systems, NTFS is the most popular in today’s world. Directories can again be present inside another directory giving it a hierarchical structure. Files can be collectively present inside a directory. Each group of data is referred to as a “file”.Ī “file system” is the structure and logic rules that are used to organize groups of data and their names. The data is easily extracted and identified by splitting it into bits and giving each one a name. Data deposited in a storage medium without a file system would be one huge body of data with no way of knowing where one piece of data ends and the next begins. The operating system’s file system is a mechanism and data structure for controlling how data is saved and accessed. What is a Database Management System (DBMS)?.Background tasks like Time Machine backups would get demoted. Reportedly, Apple’s QoS would prioritize user operations such as active windows. On your router it employs user-defined rules to give selected tasks the most bandwidth. QoS prioritizes bandwidth usage to avoid slowing down priority tasks. You may have seen the term Quality of Service (QoS) in your router’s setup instructions. This can make backup simpler and more reliable. Considering the ungainly disappointment of hard links that Time Machine has become, this could be a major upgrade. As the file system changes, only modified bits are saved. A snapshot is a read-only mountable image of a file system at a point in time.

Snapshots are a major upgrade and are brought to you in part by copy-on-write architecture. Until the write operation successfully completes, the old file is the canonical version. Only when the new file is successfully copied is the old file purged.
Copy-on-write avoids the problem by writing changes to free disk space instead of overwriting old files. As the clone diverges from the original copy, those changes (and only those changes) are saved.Ĭopy-on-write also improves data integrity. Under other systems if your volume unmounts with overwrite operations pending, you might find part of your file system out of sync with the rest. However, no bits are copied until the cloned file is modified. APFS instead creates a clone by manipulating metadata and allocating disk space. Cloning and Data IntegrityĪPFS uses a scheme called copy-on-write to make instant clones of duplicated files. Under HFS+ when a user duplicates a file, every single bit is copied.

Though it’s a major upgrade for Apple users, it seems mostly like Apple is catching up to other systems, rather than overtaking them. Nevertheless, the update isn’t a day too soon. It still works (maybe surprisingly well), but it’s not winning any medals.ĪPFS isn’t so much an upgrade to HFS+ as it is a quantum leap forward … to the present. HFS, its progenitor, is older than the Tom Cruise bromance flick “Top Gun.” It’s sort of like an old Toyota. HFS+, the file system that ships with new Macs today, is eighteen years old. Different file systems take different approaches to this task. As computers have become faster, newer file systems have taken advantage of the boost to offer new features and adapt to modern storage needs. To review quickly, a file system is the basic structure an operating system uses to store and retrieve data.
