The network driver can provide a variety of administrative functions to allow File Manager to keep up-to-date information about directories on network servers.
| Function | Description |
| WNetDirectoryNotify | Notifies File Manager of changes to a network directory. |
| WNetGetDirectoryType | Retrieves the type (normal or network) of a given directory. |
In Windows 3.1, these administrative functions are limited to modifying directory icons, and getting notification of directory manipulations.
