I want to calculate a directory(e.g- XYZ) size which contains sub folders and sub files. I want total size of all the files and everything inside XYZ.

I could find out all the folders inside a particular path. But I want size of all together. Also I see

display(dbutils.fs.ls("/mnt/datalake/.../XYZ/.../abc.parquet"))

gives me data size of abc file. But I want complete size of XYZ.
