You can also write your own provider if you need a different backend. See the code in `src/providers` for details.
####IDBFS.FileSystem.adapters - Adapters for Storage Providers
IDBFS based file systems can acquire new functionality by using adapters. These wrapper objects extend the abilities
of storage providers without altering them in anway. An adapter can be used with any provider, and multiple
adapters can be used together in order to compose complex functionality on top of a provider.
There are currently 4 adapters available:
* `FileSystem.adapters.AES(passphrase, provider)` - extends a provider with [AES encryption](http://code.google.com/p/crypto-js/#AES)
* `FileSystem.adapters.TripleDES(passphrase, provider)` - extends a provider with [TripleDES encryption](http://code.google.com/p/crypto-js/#DES,_Triple_DES)
* `FileSystem.adapters.Rabbit(passphrase, provider)` - extends a provider with [Rabbit encryption](http://code.google.com/p/crypto-js/#Rabbit)
* `FileSystem.adapters.Encryption(passphrase, provider)` - a default encryption adapter that uses [AES encryption](http://code.google.com/p/crypto-js/#AES)
```javascript
var FileSystem = IDBFS.FileSystem;
var providers = FileSystem.providers;
var adapters = FileSystem.adapters;
// Create a WebSQL-based, Encrypted File System.
var webSQLProvider = new providers.WebSQL();
var encryptionAdatper = new adapters.Encryption('super-secret-passphrase', webSQLProvider);
var fs1 = new FileSystem({ provider: encryptionAdapter });
```
You can also write your own adapter if you need to add new capabilities to the providers. Adapters share the same
interface as providers. See the code in `src/providers` and `src/adapters` for many examples.
####IDBFS.Path
