Remove dataset downloaded by dataset library from local computer

Hi ,
Currently I have downloaded dataset “wmt19” with python library dataset in my WSL2 Ubuntu distro but now I want to delete this dataset but I cannot find where it located.

Could somebody tell me where is the dataset locate, or did it have function for remove dataset from local.
Also I accidently delete cache data in .cache/huggingface. I’m not sure it will be any consequence here ?

I just found that It was a problem with WSL unable to reclaim space after delete file.
