How I can open an existing file?
Thank you.

File file = new File(filePathName);
FileInputStream inStream = new FileInputStream(file);

Thank you.
How can I write on append mode, now?

That link will answer almost any conceivable question about the i/o

File outputFile = new File(filePath);
FileOutputStream outStream = new FileOutputStream(ouputFile, true);
