complete csv entity:file example?

I succeeded in importing nodes, comments (could even keep comment ids with a trick), but I am fighting with the files for too long now .. theme/glue module that enhances Drupal's core forum module. The included styles provide the look typically found in stand alone forum software and the code provides some of the functionality, mostly related to the end user experience. By adding other Drupal contributed modules, many of which are automatically used by Advanced Forum, you can achieve much of what stand alone software provides. Because it uses the core forum module, it uses the node and comment system built into Drupal and is completely integrated, not a bridge.

please help.

I didn't find the right solution from the internet.
