How to save file in appdata

Question

What's the path, I have to use to read and write a File which is in the appdata?

Can I use ImageIo or do I have to use something else. And can I use BufferedReader and BufferedWriter?

Answer 1

APPDATA is an environment variable in Windows, so just build your paths including that directory, which you can get via System.getenv("APPDATA").

So, for example

File imageFile = new File(System.getenv("APPDATA") + "\\whatever\\picture.jpg");
