/** @file

Instance of file explorer Library based on gEfiFileExplorerProtocolGuid.
|
||
|
|
|
||
|
|
Implement the file explorer library instance by wrap the interface
|
||
|
|
provided in the file explorer protocol. This protocol is defined as the internal
|
||
|
|
protocol related to this implementation, not in the public spec. So, this
|
||
|
|
library instance is only for this code base.
