 |Parameter|Default value|Required|Description|
 |:---|:---|:---|:---|
+|`workingDir`|-|No| Use this parameter to switch between multiple directories where multiple directories contain data with the same file structure. For example, the values of `path` and `failDataPath` configured below will automatically change to `./data/student` and `./data/err/student`. The parameters can be absolute or relative.|
 |`logPath`|-|No|Path for exporting log information, such as errors during import.|
 |`files.path`|-|Yes|Path for storing data files. If a relative path is used, the path is merged with the current configuration file directory. You can use an asterisk (\*) for fuzzy matching to import multiple files with similar names, but the files need to be the same structure.|
 |`files.failDataPath`|-|Yes|Insert the failed data file storage path, so that data can be written later.|
