The same file is copied from there to our specified location. If you understood how single file upload works, then multiple file upload is very easy. FileUploadInterceptor saves all the files in request to temp directory and we can use Array or List to get their reference in action classes. Action class is similar as single upload, except that the variables are now array or list to hold multiple values. We are iterating the array and saving each file to specific directory.
