Yes, you can. As we know, there is a 32GB limitation of drive that can be formatted to FAT32 in Windows. That's because Microsoft prefers users to use NTFS instead of FAT32 for large capacity. In addition, the newer versions of Windows only support NTFS and ExFAT for a 64 GB memory stick, so you can't format it to FAT32 without help. 

You need to use reliable third-party software - EaseUS Partition Master, which can break the size limit to format a 64 GB or even larger USB flash drive to FAT32. In addition, it uses a professional partition manager that can finish the format process without capacity adjustment or USB corruption. Beyond FAT32, this tool also supports formatting your storage device to NTFS, Ext2, and Ext3 file systems.

Install this software on your PC and refer to the easy steps to format your 64 GB USB to FAT32:
