Of course there is. Many ways in fact. But only if the provider of the file
is cooperating. One of the most common ways is to compare the MD5 hash
values (go to Google and ask it to "define: MD5") of the sent and received
files. Additionally if the file in question is a ZIP archive it will be
checked for corruption before the contents are extracted -- but this is less
robust that using MD5.
