Enumerator.moveFirst()

enumeratorobj.moveFirst()
Description
The moveFirst() method of the Enumerator object moves the enumerator to the beginning of the collection. If the collection is empty or undefined, undefined is returned.
Example
In Listing 9.44, the enumerator is used to access the drive letters and types. The moveFirst() method moves the enumerator back to the beginning of the collection so the drive status can be determined for each drive.
