Final answer:
macOS reduces file fragmentation through its file system, called APFS (Apple File System), which uses the technique of copy-on-write to store modifications as new versions of files.
Step-by-step explanation:
macOS reduces file fragmentation through its file system, called APFS (Apple File System).
The APFS is designed to optimize storage by reducing fragmentation and improving performance. It does so by using a technique called copy-on-write, where any modifications to a file are stored as a new version of the file, rather than modifying the existing file directly.
This reduces the chances of file fragmentation, as files are kept in contiguous blocks, leading to faster file access and improved overall system performance.
