If conversion isn't required or you don't mind erasing the drive, Windows provides multiple ways to reformat your USB flash drive to exFAT. Note that all methods below delete data.
File Explorer is the easiest and fastest way for most Windows users to reformat a USB drive. It requires no technical skills and is ideal when your USB drive is readable and accessible in the system. However, it offers fewer advanced options compared to other tools, making it best for simple, straightforward formatting tasks.
Steps:
Disk Management is useful when File Explorer fails to open or format your USB, especially if the drive appears as RAW, unallocated, or reports errors. This method gives you greater control over volume structures, but the interface can feel less intuitive for beginners.
Steps:
Command Prompt provides a more precise and script-friendly method of formatting, often used by advanced users or IT technicians. While powerful, it is also more error-prone—typing the wrong drive letter can result in accidental data loss, so extreme caution is required.
Steps:
(Replace F with the correct letter of your USB flash drive; you can check it in File Explorer.)
