# MLHandActionClassifier.DataSource.labeledFiles(at:)

Creates a data source from a folder that contains videos, each named after the hand action they represent.

## Declaration

```swift
case labeledFiles(at: URL)
```

## Parameters

- `at`: The URL to a folder in the file system that contains folders of hand action videos. The data source uses each file’s name before the first period as its classification label.

## Discussion

Discussion Create a hand action data source from a directory of videos with the labeledFiles case. You must name each video file with a hand action label, followed by a period and an arbitrary string, ending with the video file’s extension. For example, you can name a hand action classifier’s training files Wave.3.mov, MoveCloser.1.mov, MoveCloser.2.mov, and so on. In this example, a hand action classifier would have at least two class labels: Wave MoveCloser
