Hello there, to do this first we need to have a table within list of file name MUST HAVE, and we will loop folder to check the existing file, if one missing we will record into one temp table, next for also check in paraller if existing file has size equal to 0 then record too, After that we will generate the task to send the email which file does not exist and which file exist but the size is equal to 0. Waiting for your response if interested. Thank you!!!
