I finally found a useful program that solved the problem about the error
message cannot delete file because it is in use by another program. It comes
down to permissions and who actually owns the file. The progam name is
aclview and is available here.

I was able to remove the files that i could not remove quite easliy once i
saw who was holding permissions. I was suprised at who had permissions.
