Unable to delete local DC from NWDS

I developed a Local DC in NWDS, it is stored in .dtc folder, i did some changes to this DC exported in to another folder say NewFolder/LatestDC project

now i would like to delete old DC and import Modified DC

NWDS is not allowing to delete Old DC

did anyone encountered similar problem

Later Manullay deleted project from .dtc folder and restarted NWDS,this time i could not see DC project, but if i start importing from NewFolder/LatestDC project. NWDS shows a message project already exists.

Regards,

Murali
