By default, curl is going to download the files to the working directory using the same names as on the remote host. If you want to put the files into a different directory, you can set the CurlDownloadSettings.WorkingDirectory property accordingly. If you want to rename the downloaded files, you can do so by specifying the output paths for each of the files at the remote URLs in the CurlDownloadSettings.OutputPaths property. In that case, the order of the output paths is going to be matched with the order of the remote URLs.
