What is the purpose of adding output file names as a field in CSV configuration?

Adding output file names as a field in a CSV configuration serves the important purpose of enabling quick identification of the source files associated with the data in the output. This capability is particularly beneficial in scenarios where multiple files are being processed or when data might come from various sources. By including the file name as a column in the resulting data set, users can easily reference back to their original data sources, making it simpler to audit, validate, or analyze the data later on. This practice enhances data management and clarity, which is vital for effective data analysis and reporting.
