APFS and exFAT explained

APFS(Apple file system) is a proprietary file system developed and deployed by Apple Inc for Mac computers. It made its debut on macOS 10.13 and replaced the previous Mac OX Extended as the default file system on macOS High Sierra and later. Featured with strong encryption, space sharing, snapshots, and so forth, APFS is the most powerful file system for modern Macs. 

However, the limitations of APFS are obvious. It is optimized for SSDs and flash drives, therefore it could be unfriendly for other types of storage media, including HDDs and Fusion drives. APFS is only compatible with macOS 10.13 and later, Windows and Linux can not have full read-write permissions. And APFS formatted drive for Time Machine backup can't be used on macOS Catalina or previous releases.

exFAT (Extensible File Allocation Table), another proprietary file system, is introduced by Microsoft in 2006. This newer version of FAT 32 is designed for flash drives like USB flash drives, SD cards, and so on. Although exFAT doesn't provide powerful features compared with APFS, better compatibility is the most highlighted advantage of it. It works on both Windows and macOS. 

Should I change APFS to exFAT

In case it is an internal hard drive on your Mac, especially a built-in SSD, it is recommended to use APFS on macOS High Sierra to enjoy better performance. If you attempt to run Windows on Intel Mac with Boot Camp Assistant, you can change the files system of a certain partition to exFAT so that you can access it when booting into Windows OS on your computer.

Perhaps you are using an external hard drive for Mac, so you formatted the file system as APFS to best work on Mac. Now, you need to use the APFS external disk on your Windows PC, you may find you can not read and write APFS drive on Windows due to the incompatibility issue. Hence, you want to change APFS to exFAT to use the external drive on both Mac and Windows PC. 

In a nutshell, when you want to get rid of the incompatibility of APFS, you can change APFS to exFAT to access the exFAT partition when you run Windows via Boot Camp Assistant, or use the same external hard drive on both macOS and Windows to share files, backup partitions, store documents, etc.

FAQs about changing APFS to exFAT

A

You can change the Mac hard drive formatted with APFS/HFS+ to exfat with the Disk Utility tool. Open Disk Utility, select the drive and choose Erase in the toolbar, then select the format as exFAT. When the process completes, you will get an exFAT formatted drive.

A

It depends. If you use the drive only on Mac, macOS file systems such as Mac OS Extended and APFS would be better choices which provide more powerful features combined with macOS to use. And for the sake of compatibility, both Mac and Windows offer full read and write support for exFAT. It's the better format if you frequently share files between two operating systems.

A

Yes, it does. You can only change APFS to exFAT by reformatting the drive. Without doubt, the process will remove all content stored from the drive. Once done, you will get a blank exFAT drive, and all your previous files disappear. That's why it is necessary to back up your important files before performing formatting on the drive.
