Why Cannot Format SD Card to FAT32 in Windows 10/8/7

Usually, like the USB drive, SD cards with 32GB or lower storage is set to FAT32 by default. While exFAT is set as the default file system for larger SD cards with 64GB or 128GB. As some special devices only support the FAT32 file system, like the 3Ds SD card, it requires users to format the SD card to FAT32, no matter how large it is. 

Due to the limitation of FAT32, the Windows system doesn't support creating a FAT32 partition on a more than 32GB disk partition. As a result, you cannot directly format a 64GB memory card nor USB flash drive to FAT32. So what will you do when you must format a 64GB SD card to FAT32?

Fortunately, besides the Windows built-in utility, when you cannot format your 64GB SD card or USB flash drive to FAT32, you still have a chance. A third-party & powerful FAT32 format tool can help resolve this issue effectively. Read on and download the remarkable formatting tool for help.

Here is a video tutorial for you to see how to format the SD Card to FAT32.

FAT32 vs. NTFS vs. exFAT: Which Is The Best for Your SD Card?

Besides FAT32, NTFS & exFAT are also available while formatting an SD card using Windows utilities - Disk Management, File Explorer, CMD or third-party partition manager. But do you know which is the best format for your SD card? Here in the following, we'll show you the difference between FAT32, NTFS and exFAT, and give you a suitable suggestion to choose the right file system for your SD card or USB drive.

Comparison Among FAT32, NTFS and exFAT

FAT32, exFAT, and NTFS are all compatible file systems on Windows PC. Here is a basic comparison:

Comparison FAT32 NTFS exFAT
Supported OS Windows 95/2000/XP/7/8.1/8/10 Windows 10/8/7/XP/Vista/2000 Windows Vista/7/8/8.1/10
Max Cluster Size 64KB 64KB 32768KB
Max Formatting Capacity 32GB 2TB 16EB
Max File Size 4GB 256TB 16EB

Next are a conclusion of the advantages and disadvantages of the three popular file systems that will help you understand their application case better.


  • NTFS is regarded as the most modern file system which is widely used on system drive by default.
  • FAT32 is not as efficient as NTFS, but it owns a greater compatibility with other operating systems. As for the compatibility, FAT32 is still the most widespread one. 
  • exFAT is regarded as an alternative file system to replace FAT32, with greater compatibility than NTFS on more devices and operating systems. 


  • NTFS: No realistic file-size or partition size limits.
  • FAT32: 4 GB maximum file size, 8 TB maximum partition size.
  • exFAT: No realistic file-size or partition size limits.

Which File System Should You Choose for SD Card?

Which file system should you choose for your SD card or USB drive? Follow the suggestions below to set a suitable format for your devices:


Applies to: Small SD card, USB drive with 32GB or smaller storage, gaming storage card, etc.

If your SD card storage is smaller than 32GB, and you don't plan to store large files (larger than 4GB for a single file) on the card, FAT32 is the best format.

Whenever you need to convert NTFS to FAT32 on 64GB SD card or 128GB USB drive, you can apply EaseUS Partition Master with the steps on this page for help.


Applies to: Cellphone storage, camera, digital camera, camcorder, GoPro, DJI Drones, etc. large SD cards.​

If your SD card or USB is 64GB or even bigger, or you need to store large files (single file bigger than 4GB), exFAT is recommended. Although it's similar to FAT32 as of compatibility, it doesn't have any storage limitations. 


Applies to: Large USB drive or external hard drive, Windows hard drive partitions, etc.

NTFS is a Windows-based file system, and it adopts more advanced technology than that of FAT32 and exFAT. If you are simply using the SD card between your Windows computer and the digital device, meanwhile, do not expect any file size or storage size limitation, use NTFS to achieve the best SD card performance. Again, EaseUS Partition Master is the unique solution to convert FAT32 to NTFS without formatting or losing data.
