File Gateway: The file gateway group provides users with file storage access protocols such as SMB and NFS.
File User: The file user is the account that uses the file storage service, containing authorization information such as the username and password required for file protocol access.
File Directory: The file directory provides users with management functions for first-level subdirectories within the file system, such as creating directories, deleting directories, searching for directories, and more.
File System: The file system is the core resource for file storage, responsible for storing metadata information and file data.
