Hi,
That is a temporary file path that store the uploading data.
AjaxUploader use ".resx" to prevent the file be downloaded or executed without explicit permission.
You need move/copy the temporary file to your own folder in the FileUploaded event.
private void Uploader1_FileUploaded(object sender, UploaderEventArgs args)
{
string folder=Server.MapPath("~/UploadFiles/");
string mypath=Path.Combine(folder,args.FileName);
args.MoveTo(mypath);
}
Regards,
Terry
