You have multiple datasets to export and need them to be combined into a single file. What command should you use?

The command that is most suitable for combining multiple datasets into a single file is typically 'Concatenate files.' When you concatenate files, you essentially place the data from one file directly after the data from another, resulting in a unified dataset. This method is effective when dealing with datasets that share the same structure—such as similar columns and data types—allowing you to build a single cohesive dataset from multiple sources.

While the term 'Append using folders' may suggest a similar process, it does not accurately convey the data manipulation context required for combining datasets. Instead, 'Appending' usually refers to adding records to an existing file or database without specifying a folder structure. In contrast, 'Aggregate data' refers to summarizing or grouping data rather than merging datasets, which does not align with the need to create a single file containing all the datasets.

In conclusion, concatenating files is the most appropriate command for your requirement to export and combine multiple datasets into one file.
