Cygwin's unlink function already removes the R/O attribute if it exists, because the OS equivalent to the POSIX unlink function refuses to remove files with the R/O attribute set. I assume there's some weirdness in the handling of the R/O attribute in TrueCrypt, but that's just speculation. What you can do to help this issue along: The same as above, but run rm under strace: $ strace -o rm.trace rm -f xx The -f flag drops the interactive prompt. I added lots of debug output to the unlink functionality over time, so the rm.trace file should contain a lot of interesting details as to what's going wrong here. Just appand the rm.trace file to your next reply. Thanks, Corinna -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Maintainer cygwin AT cygwin DOT com Red Hat
