Convert a FAT or FAT32 drive to NTFS

Converting a drive using these steps will preserve the files on the drive. We still recommend making sure you have backups of all files on the drive.

  1. Find the letter of drive you want to convert. Open File Explorer, and in the left pane, look for the drive under "This PC" or "Computer."

  2. Press the Windows logo key + R to open the Run dialog box.

  3. Enter cmd to open the command prompt window.

  4. At the command line prompt, type convert drive: /fs:ntfs

    For example, if the letter of the drive you want to convert is e, you would type convert e: /fs:ntfs

Note: If you want to convert an NTFS drive back to FAT32, you need to save copies of any files you want to keep, and then reformat or partition the drive.
