 == NTFS features that are not supported in ReFS == 

 Currently the text has a list of feature that is said to be missing in ReFS: ""named streams, object IDs, short names, file compression, file level encryption (EFS), user data transactions, sparse files, hard links, extended attributes, and disk quotas"". However, reading around I saw someone saying the direct opposite that ReFS has those features and NTFS do not. Not knowing who is right, a source would be good.   "
