Hi Sachin,

For DBFS V1 used in Community Edition, there may be limitations regarding the creation of folders or changes to file structures, particularly under specific paths such as /FileStore, which is commonly used to store datasets, plots, and other files. If you encounter issues with the UI, it might be related to permissions or a limitation of the Community Edition.

Instead of relying on the GUI to create folders, you can try using the dbutils.fs.mkdirs command in a notebook to programmatically create a folder in DBFS. 

dbutils.fs.mkdirs("dbfs:/FileStore/your-folder-name")

You can also consider using the command-line interface (CLI) to achieve this. Here is how you can create a directory in DBFS using the CLI:

bash
databricks fs mkdirs dbfs:/path/to/your/directory
