ReFS (Resilient File System) supports sparse files

Hi,
According to the blog MSDN is linking to (http://msdn.microsoft.com/en-us/library/windows/desktop/hh848060(v=vs.85).aspx), ReFS doesn't support sparse files. However I tried and I've been successful to create a sparse file on ReFS. I'm running Windows Server 2012 Datacenter RTM. Does it mean sparse files are just not documented therefore not supported ?
(I've posted on http://social.technet.microsoft.com/Forums/en-US/sqldatabaseengine/thread/f05ad566-6919-418e-b986-4fe296c7655e how to create a sparse files but it's from within SQL Server.)
Many thanks

Hi,
As you said, from the MSDN blog article, ReFS will not support "named streams, object IDs, short names, compression, file level encryption (EFS), user data transactions, sparse, hard-links, extended attributes, and quotas". See:
Building the next generation file system for Windows: ReFS
This article is updated in January. For your current situation, we do not have enough information to make sure it is a change or sparese files could just be created on FeFS but not work correctly. We may need to wait for further information and I will try to contact related department for your case. Thank you for your time.
