strange output from ls -l ???

This is not a SuSE question .. more of a UNIX question. I have encountered a output from a ls -l command that i have ever seen before ... libros% ls -l qt* -rw-rw-rw-+ 1 dog wheel 75633 Aug 24 2004 qtvoke.exe Can anyone tell me what the 11th bit with the + is? This is a from a bash shell running on a Windoze system. The result is that I cannot delete the file with even a "rm -f". I have changed the premissions to 666 using chmod ......... no cigar. All comments welcome john
