I understand. I also tried it, and I couldn’t create the folder either.
To create a new folder, you can specify the desired folder name in the "DBFS Target Directory" field when uploading a file to DBFS. For example, as shown in the image, specifying FileStore/test20250122 will create a new folder named test20250122 under the FileStore directory.
By the way, in a standard Databricks environment (not the Community Edition), you can simply click "Create Folder" to create a new folder.
