+# FILE Parameter
+
+Use the file parameter to pass files (or folders, hereinafter referred to as **files**) in the working directory of the upstream task to the downstream task in the same workflow instance. The following scenarios may be used
+
+- In the ETL task, pass the data files processed by multiple upstream tasks to a specific downstream task.
+- In the machine learning scenario, pass the data set file of the upstream data preparation task to the downstream model training task.
+
+## Usage
+
+### Configure file parameter
+
+File parameter configuration method: click the plus sign on the right side of "Custom Parameters" on the task definition page to configure.
+
+### Output file to downstream task
+
+**Four options of custom parameters are:**
+
+- Parameter name: the identifier used when passing tasks, such as `KEY1` and `KEY2` in the figure below
+- Direction: OUT, which means outputting the file to the downstream task
+- Parameter type: FILE, indicating file parameter
+- Parameter value: output file path, such as `data` and `data/test2/text.txt` in the figure below
+
+The configuration in the figure below indicates that the `output` task passes two file data to the downstream task, respectively:
+
+- Pass out the folder `data`, and mark it as `dir-data`. The downstream task can get this folder through `output.dir-data`
+- Pass out the file `data/test2/text.txt`, and mark it as `file-text`. The downstream task can get this folder through `output.file-text`
+
+![img.png](../../../../img/new_ui/dev/parameter/file_parameter_output.png)
+
+### Get the file from the upstream task
+
+**Four options of custom parameters are:**
+
+- Parameter name: the position where the upstream file is saved after input, such as `input_dir` used in the figure below
+- Direction: IN, which means to get the file from the upstream task
+- Parameter type: FILE, indicating file parameter
+- Parameter value: the identifier of the upstream file, in the format of `taskName.KEY`. For example, `output.dir-data` in the figure below, where `output` is the name of the upstream task, and `dir-data` is the file identifier output by the upstream task
+
+The configuration in the figure below indicates that the task gets the folder identified by `dir-data` from the upstream task `output` and saves it as `input_dir`
+
+![img.png](../../../../img/new_ui/dev/parameter/file_parameter_input_dir.png)
+
+The configuration in the figure below indicates that the task gets the file identified by `file-text` from the upstream task `output` and saves it as `input.txt`
+
+![img.png](../../../../img/new_ui/dev/parameter/file_parameter_input_file.png)
+
+## Other
+
+### Note
+
+- The file transfer between upstream and downstream tasks is based on the resource center as a transfer, and the data is saved in the `DATA_TRANSFER` directory of the resource center. Therefore, **the resource center function must be enabled**, please refer to [Resource Center Configuration Details](../resource/configuration.md) for details, otherwise the file parameter function cannot be used.
+- The file naming rule is `DATA_TRANSFER/DATE/ProcessDefineCode/ProcessDefineVersion_ProcessInstanceID/TaskName_TaskInstanceID_FileName`
+- If the transferred file data is a folder, it will be packaged into a compressed file with a suffix of `.zip` and uploaded. The downstream task will unzip and save it in the corresponding directory after receiving it
+- If you need to delete the file data, you can delete the corresponding folder in the `DATA_TRANSFER` directory of the resource center. If you delete the date subdirectory directly, all the file data under that date will be deleted. You can also use the [Open API interface](../open-api.md) (`resources/data-transfer`) to delete the corresponding file data (delete data N days ago).
+- If there is a task chain task1->task2->tas3, then the downstream task task3 can also get the file data of task1
+- Support one-to-many transmission and many-to-one transmission
+- If you frequently transfer a large number of files, it is obvious that the system IO performance will be affected by the amount of transferred data
+
+### Example
+
+You can save the following YAML file locally and then execute `pydolphinscheduler yaml -f data-transfer.yaml` to run the Demo.
+
+```yaml
+# Define the workflow
+workflow:
+  name: "data-transfer"
+  run: true
+
+# Define the tasks under the workflow

+  - name: output

+    local_params:
+      - { "prop": "dir-data", "direct": "OUT", "type": "FILE", "value": "data" }

+# 文件参数
+
+通过配置文件参数，在同一工作流实例中，可以将上游任务工作目录下的文件(或文件夹，下统一以**文件**代替)传递给下游任务。 如以下场景可能使用到
+
+- 在ETL任务中，将多个上游任务处理好的数据文件一起传递给特定的下游任务。
+- 在机器学习场景中，将上游数据准备任务的数据集文件传递给下游模型训练任务。
+
+## 使用方式
+
+### 配置文件参数
+
+文件参数配置方式如下：在任务定义页面，点击“自定义参数”右边的加号，即可进行配置。
+
+### 输出文件给下游任务
+
+**自定义参数四个选项分别为:**
+
+- 参数名：任务间传递时使用的标识，如下图中使用的`KEY1`和`KEY2`
+- 方向：OUT, 则表示输出文件给下游任务
+- 参数类型：FILE, 表示文件参数
+- 参数值：输出的文件路径，如下图中的`data`和`data/test2/text.txt`
+
+下图的配置表示任务`output`向下游任务传递两个文件数据，分别为:
+- 传出文件夹 `data`, 并标记为`dir-data`, 下游任务可以通过`output.dir-data`获取该文件夹
+- 传出文件 `data/test2/text.txt`, 并标记为`file-text`, 下游任务可以通过`output.file-text`获取该文件夹
+
+![img.png](../../../../img/new_ui/dev/parameter/file_parameter_output.png)
+
+### 获取上游任务的文件
+
+**自定义参数四个选项分别为:**
+
+- 参数名：上游文件输入后保存的位置，如下图中使用的`input_dir`
+- 方向：IN, 则表示从上游任务获取文件
+- 参数类型：FILE, 表示文件参数
+- 参数值：上游文件的标识，为 `taskName.KEY` 的格式 如下图中的`output.dir-data`, 其中`output`为上游任务的名称，`dir-data`为上游任务中输出的文件标识
+
+下图的配置表示任务从上游任务`output`中获取标识为`dir-data`的文件夹，并保存为`input_dir`
+
+![img.png](../../../../img/new_ui/dev/parameter/file_parameter_input_dir.png)
+
+下图的配置表示任务从上游任务`output`中获取标识为`file-text`的文件，并保存为`input.txt`
+
+![img.png](../../../../img/new_ui/dev/parameter/file_parameter_input_file.png)
+
+## 其他
+
+### 备注
+
+- 上下游任务间的文件传递基于资源中心作为中转，数据保存在资源中心`DATA_TRANSFER`的目录下, 因此**必须开启资源中心功能**，详情请参考[资源中心配置详情](../resource/configuration.md), 否则无法使用文件参数功能。
+- 文件命名规则为 `DATA_TRANSFER/日期/工作流Code/工作流版本_工作流实例ID/任务名称_任务实例ID_文件名`
+- 若传输的文件数据为文件夹，则会打包成后缀为`.zip`的压缩文件再上传，下游任务接到后会解压并保存在对应目录
+- 若需要删除文件数据，可以在资源中心的`DATA_TRANSFER`目录下删除对应文件夹即可, 如直接按照日期子目录删除，会删除该日期下所有的文件数据. 也可以使用`resources/data-transfer`[Open API 接口](../open-api.md)（删除N天前的数据）删除对应文件数据。
+- 如果存在任务链 task1->task2->tas3, 则最下游任务task3也能获取task1的文件数据
+- 支持一对多传输以及多对一传输
+- 如果频繁大量传输文件，毫无疑问会因传输的数据量影响到系统IO性能
+
+### 样例
+
+你可以保存以下YAML文件到本地，然后执行`pydolphinscheduler yaml -f data-transfer.yaml`即可运行Demo.

+  name: "data-transfer"
