170 vfs_streams_xattr \- Store alternate data streams in posix xattrs
174 \FCvfs objects = streams_xattr\F[]
178 This VFS module is part of the
183 \FCvfs_streams_xattr\F[]
184 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"\&.
186 The file system that is shared with this module enabled must support xattrs\&.
188 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\&.

217 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\&.
