    Maybe trivial thing to say,
    rename($in,$out) if !-e $out
    doesn't it ?

      I'm using perl 5.12.4 on windows 7.
      Your code doesn't work in windows.

        Some questions.

        1. Active Perl or Strawberry Perl ?

        2. What shows your $_ in your program ? With my XP, it shows 8.3 style file names(For example, "Program Files"=> Progra~1).

        foreach (@files) { print "$_\n"; my $original = $_; s/canción/poesía/; rename "$directory\\$original", "$directory\\$_"; }
        What would $_ with Windows 7?.

        3. When you install Win32::Unicode,Win32::Unicode::Dir, Does this work ?

        use strict; use warnings; use utf8; use Win32::Unicode; use Win32::Unicode::Dir; my $wdir = Win32::Unicode::Dir->new; $wdir->open('./'); while ( my $file=$wdir->fetch ) { next if( $file !~ /^canción/ ); my $file_new=$file; $file_new =~ s/canción/poesía/; printW "$file ==> $file_new\n"; #moveW($file, $file_new) or die $!; } $wdir->close;
        I tried with ActivePerl. As "andalou" says, I also met the same error when calling moveW. It seems lacking XS's function which is calling Win32API. I guess Strawberry Perl works ... fine?

        I understand OP="andalou" now. If you are using Active Perl,

        ppm install " +FASSP+V2+multithreading%2Fpackages%2FWin32-Unicode.ppd"
        will remove your Win32::Unicode error messages. </code>

        This shouldn't be a problem for you, use a linux live-cd...

        If I have a file called canción, without any extension, and I want to rename it to poesía, without extension, it doesn't do it...

        It only works if the filename has at least 8 characters including point and extension. Moreover, if the $to filename, has equal or more number of characters than the $from filename and this has at least 10 characters, strange characters appear on the $to filename.

        Windows related problems I bet... avoid yourself a lot of trouble and try linux for this specific task
