Why usb over 32gb cannot be formatted to fat32 in Windows 10

In Windows 10, the native disk management tool does not allow formatting USB drives larger than 32GB to the FAT32 file system. This limitation is due to the design of the file system itself. FAT32 has certain restrictions that make it incompatible with larger drives. The main limitation is related to the maximum file size and partition size supported by FAT32.

Here are a few reasons why USB drives larger than 32GB cannot be formatted to FAT32 using the native tools in Windows 10:

  • Maximum File Size: FAT32 has a maximum file size limit of 4GB. This means that you cannot store individual files larger than 4GB on a FAT32-formatted drive. With larger USB drives, such as 64GB, 128GB, or higher, it's common to have files that exceed this limit. Therefore, FAT32 is not a suitable file system for handling large files.
  • Partition Size Limit: FAT32 has a partition size limit of 32GB. This means that you cannot create a single partition larger than 32GB using FAT32. If you try to format a larger USB drive to FAT32, the native Windows tools will force you to use exFAT or NTFS instead.

To overcome this limitation and format USB drives larger than 32GB to FAT32, you can use third-party disk management tools or command-line utilities that provide additional formatting options. These tools can bypass the restrictions imposed by the native Windows tools and allow you to format larger USB drives to FAT32 if needed. However, it's important to note that using third-party tools may have its own risks, so make sure to use a reliable and reputable software.
