You do realize you posted this under C# right?

Hi,

Try this:
Java
FileWriter writer = new FileWriter("file.txt");
writer.write("Some text to append...");
writer.close();

If a file contains "This is text.", and if you execute this code, then your text file will contain this:
This is text.Some text to append...

If you want a new line after "This is text", then use the escape sequence for a new line:
Java
FileWriter writer = new FileWriter("file.txt");
writer.write("\nSome text to append...");
writer.close();

In that case, your text file will contain this:
This is text.
Some text to append...

Hope this helps.

If you want to clear a file, and then writing, have a look here:
