URL: http://svn.reactos.org/svn/reactos?rev=68268&view=rev Log: [NTFS] Don't attempt to read the unnamed stream of the $DATA attribute of each file matching: - We don't need such attribute later on - In case there's no such unammed stream, finding the file fails, whereas the file really exist
This fixes (at least here) browsing Win7 NTFS system drives, where our driver was always failing on pagefile.sys
