Early builds of Windows 8 reveal a new file system codenamed as “Protogon”.

The “Protogon” file system has been rumored to be a sub-child file system of NTFS which will be named as NTPFS, as it’s is supported with NT Protogon FS kernel mode driver.

Early tests of the Protogon file system indicates that it indeed works faster than NTFS file system on Windows 8, and it occupies less space on disk when comparing with NTFS and FAT32 or FAT.

At this point though, it’s not clear that the new file system will be included on final release of Windows 8.

In order to create a partition or volume which has the Protogon, a drive, partition or volume has to be reformatted to convert to Protogon file system, with the following steps:

  1. Press Ctrl + Shift + F10 to open Command Prompt window.
  2. Type in the following command and hit Enter:
  3. format X: /FS:protogon /Q

Replace X with the actual drive letter for the drive, partition or volume which you want to format with Protogon file system.

The /Q switch makes sure that conversion to Protogon file system takes few seconds instead of long wait.

After formatting a volume as Protogon file system, a warning message of “Please be advised that the underlying format may be incompatible with near-future versions” is displayed, indicating that the file system is ready for prime time yet, and may have undergone further change in development, if the new feature makes its way to final build after all.

Note that many Windows 8 components do not recognize Protogon file system yet. For example, chkdks will treat it as RAW file system, even though Disk Management and Windows Explorer can properly show the file system as Protogon.

When an external drive with Protogon file system is attached, you will be asked to format the disk in order to use it if you unplugged the drive and reconnect it.

And, of course, the Protogon file system won’t be compatible with Windows 7, Windows XP, and all other operating systems now.
