I want to upload two ZIPs of my game. One of them is zip for the browser. The second one contains executable for Windows. When I upload a second file after uploading one, a replacement occurs instead of the desired addition. How is this problem solved? 

I understand that the question is terribly simple, but the search did not give a quick result.

If you are uploading them through the web browser, could you confirm that you are using different file names for both zip files?

If you are using butler instead, could you confirm that you are using a different channel name?

Thanks!

I used the browser. The names were the same.
