I did what you told me...! When creating the KMZ file I added the DAY +HOUR+SECONDS to the file name so it is different each time...!
class1.ifname = DateTime.Now.Day.ToString() + DateTime.Now.Hour.ToString() + DateTime.Now.Minute.ToString() + DateTime.Now.Second.ToString(); class1.fname = class1.user_id + class1.ifname + ".kmz"; // each user_id has its own file at its own date_time.. Larry, Thank you very much for your help.
