 - **Batch Processing**: Processes input tar files in configurable batches to manage resource usage.
+- **Tidy by Default**: Default settings wil delete all mid step files and keep only the original Tar files. Can be changed in config.py
 - **End-to-End Processing**: Extracts GZ files, processes DAT/ASC, and appends to CSV in a single thread per file.
 - **Concurrency**: Uses multi-threading to process individual GZ files within a batch concurrently.
 - **Cumulative Data**: Automatically appends new query results to the existing CSV files in `COMBINED_FOLDER` for each batch, ensuring no data is lost and columns are correctly aligned.
