So you already know how to do it.

Lol... . Funny. Actually, it did not occur to me. Now I know I should figure it out by writing an empty string to all the records in the file. Thanks.

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.

So you already know how to do it.
