This example uses the FileSystemObject. To use this object, the program needs a reference to the Microsoft Scripting Runtime library. Select the Project menu's Add Reference command and click on the COM tab. Select the Microsoft Scripting Runtime entry and click OK.
The code creates a FileSystemObject and iterates through the items in its Drives collection. For each drive, the program displays information from the corresponding Drive object.
Note that trying to access some of these values raises an error if the drive is not ready (for example, if a floppy drive is empty).
