 #### fs.exists(path, callback)<a name="exists"></a>
 Test whether or not the given path exists by checking with the file system. 
 Then call the callback argument with either true or false. 
 Example:
 ```javascript
 //Test if the file exists
 fs.exists('/myfile', function (exists) {
  console.log(exists ? "file exists" : "file not found");
 });
 ```
 fs.exists() is an anachronism and exists only for historical reasons. There should almost never be a reason to use it in your own code.
 In particular, checking if a file exists before opening it is an anti-pattern that leaves you vulnerable to race conditions: another process may remove the file between the calls to fs.exists() and fs.open(). Just open the file and handle the error when it's not there.
