The illustration shows a computer screen with a folder icon labeled "PDF Files" and an arrow pointing to it to indicate that this is the folder the user needs to specify in the code. There are also several PDF file icons inside the folder.

Next to the computer screen, there is a visual representation of the code, but it is highlighted with warning signs and error messages indicating potential issues with the code, such as syntax errors or incorrect function definitions.

At the bottom of the illustration, there is a CSV file icon labeled "resultados.csv", but it is crossed out with a red X to indicate that the output file may not be generated or may contain incomplete or incorrect information.
