# copyRecursive

`open fun copyRecursive(from: String, to: String, recursive: Boolean, handler: Handler<AsyncResult<Void>>): FileSystem`

Copy a file from the path `from` to path `to`, asynchronously.

If `recursive` is `true` and `from` represents a directory, then the directory and its contents will be copied recursively to the destination `to`.

The copy will fail if the destination if the destination already exists.

### Parameters

`from` - the path to copy from

`to` - the path to copy to

`recursive` -

`handler` - the handler that will be called on completion

Return
a reference to this, so the API can be used fluently
