Are you serious???
Your opening post in your very recent topic at
Each time I read from a file and close the file, the file
becomes empty the next time I want to read or write to the file. What
mechanism or function can I use to retain the content of the file in
order to add to the existing content of the file or read the file again
on the next opening of the file. I want the file to retain its content
even when I restart the computer. Thank you in advance.
