1. FAT32 format

FAT32 is a relatively common U disk format. It has wide compatibility and can be used on various operating systems. However, FAT32 has an obvious limitation, which is that it cannot store a single file larger than 4GB. This is because FAT32 uses a 32-bit file allocation table and the maximum size of each file is limited to less than 4GB. Therefore, if you need to store large files, FAT32 may not be the best choice.

2. NTFS Format

NTFS is a commonly used file system format in Windows operating systems. It supports the storage of single files larger than 4GB. NTFS has higher performance and better security than FAT32. It supports file encryption, permission control and logging functions to better protect your data. However, the NTFS format may not be fully supported on some older operating systems.

3. exFAT format

exFAT is a newer file system format, which is designed to solve the file size limitations of the FAT32 format. exFAT supports storing single files larger than 4GB with better compatibility. It is available on multiple operating systems including Windows, Mac, and Linux. Therefore, if you need to share files across different platforms, exFAT is a good choice.
