This Compare files object performs a validation check against two sets of files by comparing their properties, via a “check sum”. The comparison can be done via the creation date as the comparison factor, or it can check to ensure that the MD5 checksums match. The files are successfully compared when the comparisons of both files are the same.
Write Variables option forces package action to save variables values into the log file before the execution.
It is usually used for debugging and not recommended for production environment.
