Be sure you have write access to the folder in which the temporary file will be created. If the file is not gigantic (e.g., 100MB or more), you could just read it into a heap-based buffer, write the new text to the file and then append the contents of the buffer. That's about as simple as it gets. "Opinions are neither right nor wrong. I cannot change your opinion. I can, however, change what influences your opinion." - David Crow
