| <a id="f-is_destroyed"></a>`is_destroyed` | `bool` | 2 | True if the file has been destroyed and is no longer available. If true then only the objfilever member is valid. |
| <a id="f-data_file_version"></a>`data_file_version` | `int32` | 3 | Data file version if the file is an internal file. |
| <a id="f-size"></a>`size` | `int64` | 4 | The logical size of the file in bytes. |
| <a id="f-extension"></a>`extension` | `string` | 5 | The file extension, not including the dot (e.g. "doc"). This unencoded extension may contain characters that are not allowed in file extensions in file systems. |
| <a id="f-relevance_score"></a>`relevance_score` | `float` | 6 | Relevance score of the object. |
| <a id="f-file_ids"></a>`file_ids` | repeated [`FileID`](https://developer.m-files.com/APIs/gRPC-API/Reference/Messages/MFiles.FileID/index.md) | 7 | All file IDs of the object's LCI version. |
