@jin park​ :

It seems like there is an overlap in the path when you use dbutils.fs.ls() to list the contents of

abfss://~~@~~.dfs.core.windows.net/dejeong, which is the managed location. This may be due to the fact that the managed location is also a path, and this is causing a conflict. To navigate to the parent path, you can use dbutils.fs.ls("abfss://~~@~~.dfs.core.windows.net/dejeong/"), with a trailing slash at the end of the path. This should list the contents of the parent directory without causing any conflicts.

Alternatively, you can try using dbutils.fs.ls("abfss://~~@~~.dfs.core.windows.net/dejeong/__internal")

, which is the internal directory where managed tables are stored, instead of __unitystorage.

It's also worth noting that the behavior of dbutils.fs.ls() and list in SQL may differ, as they are different methods and may handle paths differently.
