Thank you for your reply. I’ve checked the link you provided. I have a question and a concern. The attached files are supposed to be temporarily stored and then automatically deleted. However, they are being deleted before I have a chance to review them, causing inconvenience. Although I haven’t measured the time accurately, I have confirmed that all files become inaccessible with a 404 error within approximately one day to one week. Is it possible to set it so that the files disappear after I confirm and download them, or perhaps after six months to a year?
