A path that’s outside of the default security scope for creating a thumbnail.

```

## Discussion

The associated value is a <doc://com.apple.documentation/documentation/CoreFoundation/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(_:_:_:)`](/documentation/QuickLook/QLThumbnailRequestSetImageAtURL(_:_:_:)) or [`QLThumbnailRequestSetThumbnailWithURLRepresentation(_:_:_:_:_:)`](/documentation/QuickLook/QLThumbnailRequestSetThumbnailWithURLRepresentation(_:_:_:_:_:)).
