Accessor
Access the NTFS filesystem by parsing NTFS structures.
This accessor is a variation of the ntfs accessor. It is a bit
faster because it does not enumerate all the attributes in files
contained in directories, instead relying only on the I30 index
streams. This means it is unable to find Alternate Data Streams in
directories (because ADS are not stored in the I30 stream).
Usually the extra performance is not worth these limitations since the
ntfs accessor is pretty fast these days already.
