I am so mean, that I even give the script away now.
I think that you really should keep voting me down! (there are always going to be things that I won't understand in the world, even in nice places like PM:-( )

Note: the script might have to be run several times, because it does not delete directories when they still have files in them. - Just keep running it until 0 file and 0 directory are deleted.

#!/usr/local/bin/perl -w

use File::Find;

$workingdir = 'C:/TEMP/';

$countdirs = 0;
$countfiles = 0;
$testmode = 0;

@extensions = ('txt','obj'); #files to remove
@directories = ('win32-VC60','CVS','Cvs'); #directories to remove (rec
+ursively with all the files/subs in them)
@anymatches = ('ChangeLog'); #other special matches to remove as well

find(\&processmatch, $workingdir);

print "\n$countfiles file(s) and $countdirs director(y)(ies) were dele
+ted.\n\n";

sub processmatch{

  # Note: we are chdir in the current directory!

  $saved = $_;

  $name = $File::Find::name;

  $deleteflag = 0;

  foreach $ext(@extensions)
  {
    if($name =~ /.*\.$ext/)
    {
       $deleteflag = 1;
    }
  }
  
  foreach $dir(@directories)
  {
    if($name =~ /.*\/$dir.*/)
    {
       $deleteflag = 1;
    }
  }

  foreach $any(@anymatches)
  {
    if($name =~ /.*$any.*/)
    {
       $deleteflag = 1;      
    }
  }

  if($deleteflag == 1)
  {
    if (-d $name) 
    {
       if(!$testmode) 
     {
          rmdir $name;
       }
       print "$name\n";
     $countdirs++;
    }
    else 
    {
       if(!$testmode) 
     {
          unlink $saved;
       }
       print "$saved\n";
       $countfiles++;
    }
  }
  $_ = $saved;
}
