in thread unlink fails to delete files with perculiar names

The OP doesn't say how $targ was set.  It's merely speculation that he assigned it using a double-quoted literal. It might just as well have come from a readdir or whatever.

Also, why would unlink have returned 1, as the OP states? That should only have happened in the (unlikely) case there also was a file 'D:/Users/Dave/Documents/Personal/CV/~ Vitae - 09 June 2007.doc' around at the time of the unlink call.

    Agreed. That's why likely work.

    It might just as well have come from a readdir

    But don't you have to combine the values from readdir with the path in order to get a fully qualified path?

    Could he be doing something like  $targ = "$path/$fname";?

    why would unlink have returned 1, as the OP states?

    Not sure, but that construct looks suspect to me: my($no) = unlink $targ || carp "Unable to delete file $targ\n";.

    What ends up in $no if unlink returns 0; the return value from carp()?

      Yup
      $ perl -MCarp -e " my $f = unlink (666) || carp 1; die $f " 1 at -e line 1 1 at -e line 1.

    in my full code I get the file name using File::Find. From a windows directory listing from the command line the file is invisible, also from an explorer window...and from the application (MS word in this case) that presumeably created this as a temporary file it is also invisible.
