What is refs?

refs.sys is a system file associated with the Resilient File System (ReFS) developed by Microsoft. It is a key component of the NT ReFS file system driver in Windows operating systems. This file is responsible for managing the operations of the ReFS file system, which is designed to maximize data availability, scale efficiently to large data sets across diverse workloads, and provide data integrity by protecting against common data corruption issues.

The associated software, NT ReFS FS, is beneficial for managing large volumes of data and preventing data corruption. It is particularly useful in data-intensive fields where data integrity and availability are paramount. This includes fields like scientific research, video processing, and server hosting. The ReFS file system is also used in Windows Server operating systems for data deduplication, which is a specialized data compression technique for eliminating duplicate copies of repeating data.

The refs.sys file is needed for the proper functioning of the ReFS file system in Windows. If you're using ReFS, you should not remove this file as it could cause system instability or data loss. If you're not using ReFS and you find this file on your system, it could potentially be a disguised malware. In such cases, it would be advisable to run a malware scan and remove it if it's flagged as malicious.
