Tip of the Day: ReFS not a replacement for NTFS

Today’s tip…


Windows Server 2012 comes with a new file system, ReFS (Resilient File System).  This file system is not meant to be a replacement for NTFS.  It is merely meant to handle a small subset of what NTFS does.  There are a number of things in NTFS that are not part of ReFS.  Here is a reference guide that you can keep handy to help you quickly field questions.
