Since time NTFS was developed and formulated in the Windows operating system, data storage requirements have changed radically. There was an urgent need for a next generation file system that would work well and solve the problems that existed in NTFS. It was then that Microsoft named and developed the plans ReFS (Resilient File System) in 2012 – and was introduced in Windows 8.1 and Windows Server 2012 . ReFS was designed to maximize data availability and reliability even if the affected storage devices had a hardware failure.

Since the advent of storage devices, storage space requirements have increased exponentially. Even several terabytes of storage devices are common today. At the same time, it created the need for a reliable structure at all times. ReFS has an architecture designed to work with extremely large data sets without sacrificing performance. In this manual, we will see how to enable or disable the ReFS file system under Windows 10 and try to format a drive, but first we need to look at some important features of this file system.

In this article we will talk about the features of the Resilient File System and see how enable or disable the ReFS file system in the Windows Server operating system and try to format the drive with this file system.

Data availability : The ReFS file system increases data availability by demonstrating resistance to data corruption or errors. Automatic data integrity checks help keep ReFS online and you almost never experience downtime.

Train scalability: Data volume and size requirements increase with technological development. ReFS offers the ability to challenge and work with very large amounts of data without performance issues.

Acute error correction: The ReFS file system comes with an automatic data integrity scanner, known as Scrubber , which periodically scans the data volume, identifies potentially damaged areas and processes them for repair.

Which file system does Windows 10

If it is a standard installation, the operating system uses NTFS structures. A Windows 10 operating system that fails with storage space enabled is the ReFS + NTFS file system.

Enabling the ReFS file system under Windows 10

Now that you know that ReFS was created to address the limitations of the NTFS file system, let’s see how to enable it on your Windows 10 system and use it to format an external drive.

Before making changes, be sure to create a system restore point. If a problem occurs in the future, you can use this restore point to reset the changes.

1 Press Windows + R on your keyboard to execute the prompt. Type regedit.exe and press Enter to open the registry editor.

2 Navigate to the path below in the left pane of the Registry Editor.


3. create a DWORD WORD and name it RefsDisableLastAccessUpdate. Set its value to 1 to enable it.

(4 Then navigate to the bottom path in the left pane.


5 If the MiniNT key (16) does not exist, you can right-click it > New >Create key.

Create a new DWORD under this key and name it AllowRefsFormatOverNonmirrorVolume and set its value to 1 to enable it.

(6. disconnect from time to time to allow changes to take effect. You can now connect an external device and select the ReFS file system to format it. You can also open the sheet Properties of any drive to see which file system it is assigned to.
