```

## Discussion

Discussion The associated value is a CFString. By default, the Quick Look feature only accepts files within the current document bundle. To generate thumbnails for files at a different location, use kQLThumbnailPropertyBaseBundlePathKey with QLThumbnailRequestSetImageAtURL(_:_:_:) or QLThumbnailRequestSetThumbnailWithURLRepresentation(_:_:_:_:_:).
