Analyzing and Visualizing Data with Microsoft Excel — Question 28

Your network contains a folder that has data files in various formats.
You need to identify how many files of each extension type are in the folder by using Query Editor.
What should you do?

Answer options

Correct answer: B

Explanation

The correct answer is B because using a folder source allows you to access all files within the folder and group them by their extension. Options A and C incorrectly suggest using a file source, which does not provide the necessary access to all files in the folder. Option D incorrectly uses the Count Values command, which is not suitable for counting file types.
