Which Files Are Evaluated and Analyzed? 
The reputation service evaluates most file types. File type identification is determined by file content and 
is not dependent on the filename extension. 
Some files with unknown reputation can be analyzed for threat characteristics. When you configure the 
file analysis feature, you choose which file types are analyzed. New types can be added dynamically; 
you will receive an alert when the list of uploadable file types changes, and can select added file types 
to upload.
