Hi smacdonald2008​, thanks for your response.I am able to download the file but my requirement is when we are downloading the asset folder and if we select the mail option along with asset download that time its not triggering the mail when asset size is larger than 3 GB.I am getting the download link on my mail for the asset folder when the size is less than 3GB.
