## Filtering existing reports

You can filter existing reports that were initially generated without applying a knownissues.xml file.

To filter reports:

1. Do either of the following:
   - Click Report Filter Wizard on the toolbar.
   - Right-click the report of your choice and select Filter.
2. In the dialog, click Add Files to locate the report files (.xml) from the file system.
3. Click Browse to define the target location for the filtered reports.
4. (Optional) Click Configure knownissues file to change the applied knownissues.xml file.

   See instructions in Configuring the knownissues.xml file.

5. Click Finish to start filtering.

The results are listed on the Compatibility Analyser view. To open a report, double-click it on the list. See Viewing the reports for more information.
