    What code have you already written and where do you encounter problems?

    You might want to read File::Find.

    You are probably thinking of glob constructs, which are different to regular expressions. In your example D:/Settings/* (not sure why you used //), "*" in globbing means a filename consisting of "zero or more of any valid character", whereas in a regular expression that would be ".*". The "*" is a quantifier, it quantifies the character, or group of characters, to its left. The dot "." in regular expressions mean one single character, whereas in globbing that would be "?".

      $val="D:\\VmWare\\*";
find(\&print_name, "$val");

sub print_name
{
    push(@array_name,$File::Find::name);
}

foreach $val(@array_name)
{
print "$val \n";
}
