Many a times when you start using a downloaded file it fails. Generally the error messages
Though you cannot avoid this type of error but there is away to make sure what you have downloaded is not broken when you use it in future. Its called as File Integrity test. These tests make sure you had exactly the same bits of file what you created on server and downloaded on your machine.
There are couple of algorithms like sum, md5sum, sha1sum, and sfv which generate a unique hash code, if you can test it after download and see if hashcode matches, this means you have a file which exactly was on server.

This way you an now check the downloaded file and match the checksum which is generally given on many sites.
