* in the file name.
*
* For case-sensitive file systems all file names are normalized by definition.
* For case-insensitive file systems that implement file name normalization,
* a normalized file name is the one that the file system specifies in the
* response to Create or Open (see also FspFileSystemGetOpenFileInfo). For
* case-insensitive file systems that do not implement file name normalization
* a normalized file name is the upper case version of the file name used
* to open the file.
