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);
