Check for Correct File Name Syntax

Question

What is the most efficient way to check if a String can be used as a file name? Here is my current (bulky) way:
public static boolean isValidFileName(String s) {
     try {
          File file = new File(s);
          file.mkdir();
          file.delete();
          return true;
     catch (Exception e) {
          return false;
Thanks!

Sorry about the poor code format, above. This is my first posting experience here.
public static boolean isValidFileName(String s) {
     try {
          File file = new File(s);
          file.mkdir();
          file.delete();
          return true;
     catch (Exception e) {
          return false;
}
