Which of the following statements correctly describes loading multiple files with one Input Data Tool?

The choice emphasizes that the Input Data Tool in Alteryx can be configured to read multiple files simultaneously, particularly using wildcard functionality or specifying a common pattern. By using a syntax like *Returns 2019.csv, you can instruct Alteryx to load all files that match specific criteria, such as files that share a common prefix or suffix in their name. This capability is particularly useful for handling batches of similarly structured data files efficiently.

In contrast, other options present limitations that are not present in the functionality of the Input Data Tool. For instance, selecting each file individually or only being able to load the first file fails to take advantage of the bulk loading capabilities provided by Alteryx. Additionally, the idea that data types must be identical across files is misleading; while uniformity in data structure is beneficial for processing, it is not a strict requirement, as Alteryx can handle files with different data types through data preparation steps post-loading.
