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:
- Usually higher performance, especially when using it with virtual machines.
- The theoretical volume size is 262144 exabytes (vs 16 for NTFS!)
- The absence of a file path limit of 255 characters (32768 characters in ReFS)
- "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
- ReFS does not support compression, additional attributes and file system encryption opposite to NTFS
- For ReFS the Bitlocker encryption is used
