Setting Up Discovery Server : Discovery Server Options : Enabling binary files content inspection
  
Enabling binary files content inspection
The Binary Files Content Inspection option allows for inspecting text content held in arbitrary binary files. When this option is disabled, DeviceLock performs keywords- and pattern-based content discovery for only Unicode text held in known file types. For a list of known file types, see Expansive coverage of multiple file formats and data types in the ContentLock and NetworkLock section.
When this option is enabled, DeviceLock performs keywords- and text pattern-based content discovery for text held in any binary files, regardless of text encoding (Unicode or non-Unicode). In this case, content discovery may take considerably longer to complete.
 
Note: This option affects discovery rules that employ keywords groups, pattern groups and/or complex content groups containing those group types. For details regarding discovery rules, see Rules and Actions.
To enable or disable this option, double-click the Binary Files Content Inspection item in the Discovery Server Options list, or right-click that item and then choose Enable or Disable.
