# Core Actions Reference
Core Actions are primitives implemented by the Dagger Engine itself. They can be combined into higher-level composite actions. Their definitions can be imported in the `dagger.io/dagger/core` package.
For more information about Dagger Actions, see [Dagger Actions](../core-concepts/1221-action.md).
The following core actions are available:
## Core Actions related to filesystem trees
| Definition | File | Description |
| :----------- | :-------------------------------------------------------------------------------------- | :-------------------------------------------------------------------- |
| `#Copy` | [fs.cue](https://github.com/dagger/dagger/blob/v0.2.4/pkg/dagger.io/dagger/core/fs.cue) | Copy files between two filesystem trees |
| `#Diff` | [fs.cue](https://github.com/dagger/dagger/blob/v0.2.4/pkg/dagger.io/dagger/core/fs.cue) | Extract the difference between two filesystems as its own file system |
