When you download files, you receive a CSV file that helps you keep track of what you downloaded. This CSV file contains important information about each downloaded file, such as its type, ID, name, owner, and file path. 

If you chose to download files in subfolders within a ZIP archive, the CSV file also shows the file's parent ID and name. By looking at the CSV file, you can verify that all the files you intended to download are listed, making sure nothing is missing.
