### Using with other modules that modify `fs`
When you require `mock-fs`, Node's own `fs` module is patched to allow the binding to the underlying file system to be swapped out. If you require `mock-fs` *before* any other modules that modify `fs` (e.g. `graceful-fs`), the mock should behave as expected.
**Note** `mock-fs` is not compatible with `graceful-fs >= 3.0.0` and therefore not compatible with `gulp >= 3.7.0`.
### `fs` overrides
The following [`fs` functions](http://nodejs.org/api/fs.html) are overridden: `fs.ReadStream`, `fs.Stats`, `fs.WriteStream`, `fs.appendFile`, `fs.appendFileSync`, `fs.chmod`, `fs.chmodSync`, `fs.chown`, `fs.chownSync`, `fs.close`, `fs.closeSync`, `fs.createReadStream`, `fs.createWriteStream`, `fs.exists`, `fs.existsSync`, `fs.fchmod`, `fs.fchmodSync`, `fs.fchown`, `fs.fchownSync`, `fs.fdatasync`, `fs.fdatasyncSync`, `fs.fstat`, `fs.fstatSync`, `fs.fsync`, `fs.fsyncSync`, `fs.ftruncate`, `fs.ftruncateSync`, `fs.futimes`, `fs.futimesSync`, `fs.lchmod`, `fs.lchmodSync`, `fs.lchown`, `fs.lchownSync`, `fs.link`, `fs.linkSync`, `fs.lstatSync`, `fs.lstat`, `fs.mkdir`, `fs.mkdirSync`, `fs.open`, `fs.openSync`, `fs.read`, `fs.readSync`, `fs.readFile`, `fs.readFileSync`, `fs.readdir`, `fs.readdirSync`, `fs.readlink`, `fs.readlinkSync`, `fs.realpath`, `fs.realpathSync`, `fs.rename`, `fs.renameSync`, `fs.rmdir`, `fs.rmdirSync`, `fs.stat`, `fs.statSync`, `fs.symlink`, `fs.symlinkSync`, `fs.truncate`, `fs.truncateSync`, `fs.unlink`, `fs.unlinkSync`, `fs.utimes`, `fs.utimesSync`, `fs.write`, `fs.writeSync`, `fs.writeFile`, and `fs.writeFileSync`.
