If you’ve got an external hard drive or USB flash drive formatted with the FAT32 file system in Windows 10, you might need to convert FAT32 to NTFS in Windows 10 for some reasons.


FAT32 is a legacy file system created in 1980s and was used by default with a number of Windows versions. It only supports the maximum partition capacity of 32 GB in Windows, 2TB on MacOS. Besides, a single file stored on the FAT32 partition cannot exceed 4GB. That’s might be the main reason for which users want to convert FAT32 to NTFS in Windows 10.

By contrast, NTFS(New Technology File System) is a modern file system for computer hard drive. It provides several improvements over the earlier FAT file system, including file and folder permissions, encryption, and file compression.

  • Support larger partition and file size (No realistic file-size or partition size limits.).

  • More efficient disk space management.

  • Support partition, folder and file compression.

  • Reasonable system sources allocation improves system security.

  • Access permission for shared source, folder and file enables higher security.

How to convert FAT32 to NTFS in Windows 10 without data loss?

To change FAT32 file system to NTFS, there are three methods available.

Step 2. Then you will be asked to type the current volume label of the drive. After entering the label name, the conversion process will start. Once it gets completed, you will get a message in command prompt saying Conversion Complete.

Limitations of converting FAT32 to NTFS with Command Prompt:

  • Once you convert FAT to NTFS, you cannot convert it back to FAT or FAT32 and you will receive an error message saying “Convert is not available for NTFS drive”. You will need to reformat the drive or partition to FAT32.
