| Field | Type | Description |
| --- | --- | --- |
| file\_id | String | Identifier for this file, which can be used to download or reuse the file |
| file\_unique\_id | String | Unique identifier for this file, which is supposed to be the same over time and for different bots. Can't be used to download or reuse the file. |
| file\_size | Integer | *Optional*. File size in bytes. It can be bigger than 2^31 and some programming languages may have difficulty/silent defects in interpreting it. But it has at most 52 significant bits, so a signed 64-bit integer or double-precision float type are safe for storing this value. |
| file\_path | String | *Optional*. File path. Use `https://api.telegram.org/file/bot<token>/<file_path>` to get the file. |
