I have deleted files from WORKAREA and want to delete the same using iwsubmit command.

\>iwsubmit.exe -x -u Y:/default/WORKAREA/templat
edata/ContentType/Article/data/en/VFF_Test1 "test";
I got the following error
ERROR:02006: Error locating Y:/default/WORKAREA/tem
platedata/ContentType/Article/data/en/VFF_Test1
VFF_Test1 had been deleted from workarea.
Tell me the correct way to use iwsubmit command.
is there any other command to delete file from stagging?
Please help me !
