- **Startup Safety Check**: Scans the `COMBINED_FOLDER` at startup and warns the user if existing files are found, offering a chance to abort to prevent accidental data mixing.
- **Startup Safety Check**: Scans the `COMBINED_FOLDER` at startup and warns the user if existing files are found, Deleting existing files if continue is accepted.
- **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.
