Q.  How can I make a file or folder world readable?

A.  At or after OS Level 9 use setReadable:

boolean makeWorldReadable(final String filename) {
	File f = new File(filename);
	return f.setReadable(true, false);
}

Before OS Level 9, use chmod:

boolean chmod(final String file, final int mode) {
	final String strMode = String.format("%o", mode);

	boolean result = false;
	try {
		Process p = Runtime.getRuntime().exec("chmod " + strMode + " " + file);
		result = true;
	} catch (IOException e) {
		result = false;
	}

	return result;
}

Example use for a file:

chmod("myfile.txt", 0666);

Example use for a folder:

chmod("myfolder", 0777);
