Differences between the ReFS and NTFS

In addition to the functionality related to a data integrity maintainance on media, ReFS has the following main differences from the NTFS:

  1. Usually higher performance, especially when using it with virtual machines.
  2. The theoretical volume size is 262144 exabytes (vs 16 for NTFS!)
  3. The absence of a file path limit of 255 characters (32768 characters in ReFS)
  4. "DOS file names" are not supported in ReFS (i.e., accessing the C:\Program Files\ folder on the C:\progra~ 1\ path will fail). In NTFS, this feature was retained for compatibility with older software
  5. ReFS does not support compression, additional attributes and file system encryption opposite to NTFS
  6. For ReFS the Bitlocker encryption is used
