Unrecognized Files

Unrecognized files are files that are stored on remote machines and not recognized by Universal Discovery. The information about these files are usually imported and stored by the Data Flow Probe. For more information on how to configure the XML Enricher to import unrecognized files, see XML Enricher: Software Recognition Configuration Dialog Box.

Periodically, you may want to remove unrecognized files for the following reasons:

Large amounts of unrecognized files are causing performance problems
Large amounts of unrecognized files are consuming large amounts of hard drive space
You have deleted a Node CI instance for a node, and you want to remove unrecognized files that are associated with the deleted node

You can remove all unrecognized files, or you can remove unrecognized files that reach an aging threshold.

To clean up all unrecognized files, see How to Clean Up Unrecognized Files.

To clean up aged unrecognized files, see How to Clean Up Aged Unrecognized Files.
