" kb<br>"; echo "temp file: " . $_files["file"]["tmp_name"] . "<br>";  if (file_exists("c:/inetpub/wwwroot/" . $_files["file"]["name"]))   {   echo $_files["file"]["name"] . " exists. ";   } else   {   move_uploaded_file($_files["file"]["tmp_name"],   "c:/inetpub/wwwroot/" . $_files["file"]["name"]);   echo "stored in: " . "c:/inetpub/wwwroot/" . $_files["file"]["name"];   } }   } else   {      echo "invalid file";   } ?>

thanks in advance.

i don't think mime type .txt files correct. try txt/plain instead of txt/text in if statement.
