Use hashes instead of arrays.
Comparing filesize is not the best way to determine if the file has been changed. You should compare the contents. The best approach to that would be to generate an md5 checksum and compare those.
So, your hash keys will be the filenames and the value of each is the md5 checksum/digest.
Digest::MD5

Another choice would be File::Checksum
