General disclaimer: use strict/warnings.

Using a global filehandle (or in general any global variable that can be modified) with recursion is a *bad* idea. Instead use lexcials: 
opendir(my $SCR , $dir) or die "Can't open $dir: $!";
while( defined (my $file = readdir $SCR) )

Don't forget to closedir when done.
