#### 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.
