Convert NTFS to APFS

"I use a Windows 10 machine for many years but my computer recently died. I am interested in changing over to a Mac machine to learn Photoshop and video editing skills. The main issue is getting my work documents and photos that I have worked on, which are on separate NTFS external hard drives. I believe I need to go from NTFS to APFS. I am not sure how to do it and keep all my files in the same quality at the same time. Anybody can help?"

When people want to move from Windows platform to Apple platform using an external drive formatted with NTFS file system, they will always find that the files on the NTFS drives non-editable and non-transferrable on Mac.

That's because macOS can't mount NTFS drive on Mac with NTFS write support. That's to say, you can read NTFS drive on Mac but can't write to Microsoft NTFS-formatted drives on Mac.

Therefore, you must be considering converting NTFS to APFS to solve the inconvenience. This post will teach you how to convert NTFS to APFS without losing data so that you can use the external drive on Mac freely. But before converting NTFS to APFS, did you know what those two different file systems are? Did you know what advantages they have?

What is NTFS file system?

NTFS (New Technology File System) replaced FAT32 file system and became the default file system in Windows 10, Windows 8, Windows 7, Windows Vista, and Windows NT operating system. NTFS also is supported in other operating systems such as Linux and BSD. macOS only has NTFS read support and its NTFS write support is disabled by default and experimental.

NTFS has a lot of advantages compared to its former default file system FAT32. For instance:

  • It has higher security by controlling permissions to the files.
  • NTFS is optimized to be able to encrypt, decrypt, compress and decompress files.
  • NTFS deals with large files and partitions very successfully if you are using any external storage media larger than 32GB in Windows.

What is APFS file system?

APFS (Apple File System) is Apple's newest file system coming with macOS High Sierra. macOS Monterey, macOS Big Sur, macOS Catalina, and macOS Mojave use APFS as default file system as well. Windows doesn't have APFS support at all. You can't read nor write to APFS drives on Windows.

Compared with previous default file systems, HFS and HFS+, formatting external drives to APFS has a few advantages. For example:

  • It is optimized for faster read-write speed on SSDs and flash-memory devices.
  • It supports full-disk encryption and multiple copies of the same file.
  • It allows users to manage the disk storage more efficiently by having flexible free space.

There is certainly a gap between Microsoft NTFS drives and Mac operating system. If you want to use this external HD interchangeably between Windows and macOS, it is better to format external hard drive for Mac and PC with FAT or exFAT format.

On the other hand, if you are going to move to macOS permanently and use the external drive on a Mac running macOS Monterey, Big Sur, Catalina, Mojave or High Sierra, it is a good idea to convert NTFS to APFS since APFS is the primary file system in them now.
