I am totally new to linux unfortuately, I have lived a windows lifestyle. I heard about knoppix booting from cd, so i donwloaded it, and i am trying to delete something from the ntfs partition. Windows keeps blue screening because there is no free space on the HDD. When I boot knoppix and try to delete something I get this error, Could Not Delete File /*/*/*.***

Could someone point me in the right direction.
Thanks
