You can check if any file matches another by calculating something called their checksum hashes. These alphanumeric sequences are so specific that if two files match then you can be certain that they are the same. This is necessary because sometimes when downloading or transferring files they get corrupted. Even a small change in the file will greatly change the file's checksum hash. Different algorithms exist for doing this (e.g. MD5, CRC32).
