In some file transfer scenarios the receiver of a file has no knowledge about when the sender creates a file. In case of a (very) large file, it is possible for the receiver to try to read a file before the sender has finished writing it. If the receiver then attempts to use the file at this moment, he will get a corrupted, incomplete file.
