<title>DESCRIPTION</title>
<para>This VFS module is part of the
<citerefentry><refentrytitle>samba</refentrytitle>
<manvolnum>7</manvolnum></citerefentry> suite.</para>
<para>The <command>vfs_streams_xattr</command> enables storing of NTFS
alternate data streams in the file system. As a normal posix file
system does not support the concept of multiple data streams per file,
the streams_xattr module stores the data in posix extended attributes
(xattrs). The name of these attributes is
user.DosStream."ADS-NAME".</para>
<para>The file system that is shared with this module enabled must
support xattrs.</para>
<para>Please note that most file systems have severe limitations on
the size of xattrs. So this module might work for applications like IE
that stores small zone information in streams but will fail for
applications that store serious amounts of data in ADSs.</para>

<para>The original Samba software and related utilities
were created by Andrew Tridgell. Samba is now developed
by the Samba Team as an Open Source project similar
to the way the Linux kernel is developed.</para>
