1.If you have duplicate data then you can use sorter or aggregator transformation to remove duplicate.
2. If u want to delete record after 50 the row then u can use sequence genetor.
3. Write the result to a other flat file as target.
4. Use 'Post session success command' in component tab of session task to delete the old flat file and rename the target flat file to old flat file.
Please correct me if this is wrong
Thanks and regards
