Is there any possibility the directory contains subdirectories? readdir will find those, but no files in them. readdir also finds '.' and '..', which it doesn't seem you take into account. stat returns true for directories, and it returns a filesize for directories which you may or may not want.

If you want to recurse and only pick up files, perhaps this is a job for File::Find and friends, rather than readdir. There's also Win32::DirSize if you're on Windows.
