Remarks
FEF. is a Member of the FEX-Family "For Each X". They are used for easy enumeration
Limitations:
The internal data storage can hold up to several hundred Megabytes of Directory data. Yet there is no warranty that there is not a file-system out there, that is too large in size to be fully enumerated.
