How to Clean Up Aged Unrecognized Files

This task describes how to configure the Data Flow Probe to automatically remove unrecognized files that have not been used to recognize applications and are no longer needed to store.

Locate the file

Locate the DataFlowProbe.properties file in the following folder:

C:\UCMDB\DataFlowProbe\conf
Set the aging threshold

Find the UnrecognizedFileExpirationTime parameter and change the value to the number of days that the Data Flow Probe waits before deleting unrecognized files.
Note
- Default: 30 days
- The value should be longer than the longest interval used for inventory scanning.
Restart the Data Flow Probe service

Restart the Data Flow Probe. To do this, see How to Start a Data Flow Probe.
Results
