## Apple Propietary File System (APFS)
|
|
|
|
**Apple File System (APFS)** is a modern file system designed to supersede the Hierarchical File System Plus (HFS+). Its development was driven by the need for **improved performance, security, and efficiency**.
|
|
|
|
Some notable features of APFS include:
|
|
|
|
1. **Space Sharing**: APFS allows multiple volumes to **share the same underlying free storage** on a single physical device. This enables more efficient space utilization as the volumes can dynamically grow and shrink without the need for manual resizing or repartitioning.
|
|
1. This means, compared with traditional partitions in file disks, **that in APFS different partitions (volumes) shares all the disk space**, while a regular partition usually had a fixed size.
|
|
2. **Snapshots**: APFS supports **creating snapshots**, which are **read-only**, point-in-time instances of the file system. Snapshots enable efficient backups and easy system rollbacks, as they consume minimal additional storage and can be quickly created or reverted.
|
|
3. **Clones**: APFS can **create file or directory clones that share the same storage** as the original until either the clone or the original file is modified. This feature provides an efficient way to create copies of files or directories without duplicating the storage space.
|
|
4. **Encryption**: APFS **natively supports full-disk encryption** as well as per-file and per-directory encryption, enhancing data security across different use cases.
|
|
5. **Crash Protection**: APFS uses a **copy-on-write metadata scheme that ensures file system consistency** even in cases of sudden power loss or system crashes, reducing the risk of data corruption.
|
|
|
|
Overall, APFS offers a more modern, flexible, and efficient file system for Apple devices, with a focus on improved performance, reliability, and security.
|
|
|
|
```bash
|
|
diskutil list # Get overview of the APFS volumes
|
|
```
|
|
|
|
## Firmlinks
|
|
|
|
The `Data` volume is mounted in **`/System/Volumes/Data`** (you can check this with `diskutil apfs list`).
|
|
|
|
The list of firmlinks can be found in the **`/usr/share/firmlinks`** file.
