  Legacy File Event Data Structures
File Event for 5.2.x
The file event contains information on files that are sent over the network. This includes the connection 
information, whether the file is malware, and specific information to identify the file. The file event has 
a block type of 32 in the series 2 group of blocks. It supersedes block type 23. New fields have been 
added to track source and destination country, as well as the client and web application instances.
The following graphic shows the structure of the File Event data block:
