.SH "NAME"
vfs_streams_xattr \- Store alternate data streams in posix xattrs
.SH "SYNOPSIS"
.HP \w'\ 'u
vfs objects = streams_xattr
.SH "DESCRIPTION"
.PP
This VFS module is part of the
\fBsamba\fR(7)
suite\&.
.PP
The
vfs_streams_xattr
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"\&.
.PP
The file system that is shared with this module enabled must support xattrs\&.
.PP
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\&.

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\&.
