The concept of file formats and their compatibility might confuse you, so we are going to make it simple. The following are the most common file format options and we will help you choose the best for you based on the platforms you use.

NTFS: NTFS or New Technology File System was developed by Microsoft and it is the most common file format system used on Windows devices. The NTFS was developed as an improvement over FAT and HPFS file formats. Mac doesn’t recognize the NTFS file format, hence any storage devices formatted with NTFS will not be read by the MacOS.

FAT: FAT or File Allocation Table was designed for storage devices that didn’t have much storage capacity. Hence it was used for formatting floppy disks and other older storage devices. With storage devices getting more and more storage space, FAT file format could no longer keep up with the modern requirements. Hence, this file format is not commonly seen nowadays.

FAT32: FAT32 is an advanced form of FAT file format that is engineered for larger storage devices. However, FAT32 limits single file transfer to just 4GB. So if you have a file that is more than 4GB, you cannot copy it to a FAT32 formatted drive. The FAT32 file format is used in USB drives that are of smaller storage sizes.

ExFAT: ExFAT or Extended File Allocation Table was made by Microsoft in 2006 is an upgraded form of FAT32 that doesn’t have the constraints of FAT32. ExFAT removes the file transfer bottleneck of 4GB and allows unlimited file partitions. ExFAT is commonly used in modern USB devices.

MacOS Extended (Journaled): In the guide, we formatted the external USB drive with MacOS Extended (Journaled). It is also known as HFS+ file format. This is the most recent file format that Apple used for formatting external storage drives. You can also format internal drives with this file format.

External drives used on Only MacOS: If you are using your external storage devices on just MacOS, then the best option for you is MacOS Extended (Journaled). They provide the best performance for Apple PCs. However, you cannot use them with Windows PCs.

External drives compatible for both Windows and Mac: If you want your external USD drive to be compatible with both Apple and Windows devices, then choose exFAT file format. For USB devices with low storage (in the range of 4 – 8GB) formatting it with FAT32 will be the best option. Both exFAT and FAT32 file formats are compatible with both operating systems.

Part 4. How to format USB to FAT32 on Mac

As mentioned before, FAT32 is one among the very few file formats that you can use interchangeably between Windows and a Mac. So if you have a USB drive that is formatted in some other file formats, you need to first format it to FAT32 so that you can use it on Mac as well as PC.

The following steps will help you format any external USB with FAT32 file format on Mac.
