+## Overview
+
+This article explains how to clear stored File System SDD match data from the database. This approach removes the sensitive data captured in match results while keeping the scan results themselves, such as match counts and criteria.
+
+## Instructions
+
+### Excluding Sensitive Data from the Next Collection
+1. Open the **SEEK System Scan** query configuration.
+2. On the _Sensitive Data Settings_ tab, uncheck the option **Store discovered sensitive data** to prevent new match data from being stored.

+
+### Clearing Previously-Stored Match Hits
+
+In the Netwrix Access Analyzer SQL database, run the following SQL statement:
+
+```sql
+UPDATE SA_FSDLP_MatchHits
+SET MatchData = NULL,
+    MatchPrefix = NULL,
+    MatchSuffix = NULL
+```
+
+### Removing All SDD Matches
+
+Use the `FS_SDD_DELETE` instant job to remove SDD matches entirely:
