Convert Existing Disk Volumes to NTFS

Updated: August 22, 2005

Applies To: Windows Server 2003, Windows Server 2003 with SP1

The command-line tool Convert.exe converts FAT and FAT32 volumes to the NTFS file system, leaving existing files and folder intact. Volumes converted to the NTFS file system cannot be converted back to FAT or FAT32.

Requirements

  • Credentials: Membership in the Administrators group on the local computer.

  • Tools: Convert.exe

Recommendation

As a security best practice, log on to your computer using an account that is not in the Administrators group, and then use the Run as command to run IIS Manager as an administrator. At the command prompt, type runas /user:administrative_accountname mmc %systemroot%\system32\inetsrv\iis.msc.

To convert FAT and FAT32 volumes to NTFS
  1. In the Run dialog box, type convert followed by the appropriate syntax, and then click OK.
