# isPreallocateInhibited

A Boolean value that instructs FSKit not to call this protocol’s methods, even if the volume conforms to it.

## Declaration

```swift
optional var isPreallocateInhibited: Bool { get }
```

## Discussion

Discussion FSKit reads this value after the file system replies to the loadResource message. Changing the returned value during the runtime of the volume has no effect.
