Export Data From Sql Server 2005 Table To Text File

Hii
I want to transfer data from table to a text file.I m trying to use bcp utility and xp_cmdshell.but the export is not successful.
My query is:

EXEC master..xp_cmdshell'bcp "Select * from test..emp" queryout "c:dept.txt" -c -T -x'

and its output is:

NULL
Starting copy...
NULL
3 rows copied.
Network packet size (bytes): 4096
Clock Time (ms.) Total : 16 Average : (187.50 rows per sec.)
NULL


but there is no row copied into c:dept.txt

where is the problem??

Thanx
