What happens to duplicate files?

If there are several files in the Download Cart with the same name, they are all downloaded. The first file is placed in the download location, and the remaining files are placed in separate subfolders named after the file name, with a number appended to differentiate. For example, if there are four files named "image.jpg" they would be downloaded to the following locations (assuming SomeUser’s Desktop is the default download directory):

C:\Users\SomeUser\Desktop\image.jpg
C:\Users\SomeUser\Desktop\image_0.jpg\image.jpg
C:\Users\SomeUser\Desktop\image_1.jpg\image.jpg
C:\Users\SomeUser\Desktop\image_2.jpg\image.jpg

If a file with the same name already exists at the download location, it is not overwritten. The file in the Download Cart with the same name is not downloaded, and a warning message is provided to inform you that the file was not downloaded. The one exception is zip files: if you have chosen the option to zip files before download, the zip file downloaded will overwrite any zip files with the same name currently in the download location.
