Hi davies,

one possible way demonstrated under the Perl debugger: 

  DB<1> $curdir = 'Y:\Music\Schubert\Lieder\Terfel';

  DB<2> $startdir = 'Y:\Music';

  DB<3> $curdir =~ s/^\Q$startdir\E\\//i;

  DB<4> $out = join "_", split /\\/, "$curdir.pls";

  DB<5> p $out;
Schubert_Lieder_Terfel.pls

I don't know if this is any better.

You could even do it in a single code line: 

  DB<7> $curdir = 'Y:\Music\Schubert\Lieder\Terfel';

  DB<7> $startdir = 'Y:\Music';

  DB<8> $out = join "_", map {s/^\Q$startdir\E\\//i;  split /\\/, "$_.
+pls"} $curdir ;

  DB<9> p $out
Schubert_Lieder_Terfel.pls

Again, this is shorter, but I do not claim that this is any better, you decide.
