 3. **File and Directory Copying**:
    - Supports multiple copy modes:
      - **Replace**: Overwrites existing files or directories in the destination.
-     - **Update**: Copies only if the source file is newer than the destination file.
+     - **Update**: Copies only if the source file is newer than the destination file (files only).
+     - **Copy**: Creates directories, if already exsisting, only copies non existing files in that folder
    - Handles both files and directories.
    - Generates warnings and error messages if issues occur (e.g., source file not found).
