Regardless of the browser you are using, you may check the browser's default download folder for any downloaded files.
If you didn't change your default download location, then Google Chrome downloads files to the following locations: Windows 10, 8, 7 and Vista: \Users\<username>\Downloads. Mac: /Users/<username>/Downloads. Linux: /home/<username>/Downloads.
By default, Microsoft Edge places all your downloaded files in a default folder, called Downloads, located inside your user folder.
