By default, the unmatched files after data normalization get deleted automatically following a Technopedia Catalog Sync.
Below are steps to not delete the unmatched file by default:
1)Stop the Flexera Data Platform service
2)Open the file "Data Platform/Conf/Norm.Configuration.config"
3)Search for "AUTO_DELETE_UNMATCH"
4) Change the value of the "AUTO_DELETE_UNMATCH" node from "true" to "false"
5)Start the Flexera Data Platform service
