Yep your right Im only interested in the folders nothing else.

However the inline grep and directory check does not return any anything. Ive updated the directory handle to a scaler as per Ikegami's advice. 

    my @files = grep(/\w/,readdir($fh));
#returns folder & files
    my @dirs = grep {/\w/ and -d} readdir($fh);
#returns blank
