Hi Michael,
You should be able to use the Read function to retrieve the FileInfo for
the files contained in the directory pointed to by the current
EFI_FILE_PROTOCOL.
An example code snippet is below:
EFI_SIMPLE_FILE_SYSTEM_PROTOCOL *SimpleFs = NULL;
EFI_FILE_PROTOCOL *RootFs = NULL;
EFI_STATUS Status = EFI_INVALID_PARAMETER;
EFI_FILE_INFO *FileInfo = NULL;
UINTN FileInfoSize = 0;
Status = SimpleFs->OpenVolume(SimpleFs, &RootFs);
if(Fs != NULL)
{
do
{
Status = RootFs->Read(RootFs, &FileInfoSize, FileInfo);
// Quirk about the Read function, when you reach the end of
the files in the current directory, it returns success
// without any fileinfo
if(Status == EFI_SUCCESS)
break;
else if(Status == EFI_BUFFER_TOO_SMALL)
{
Status = gBS->AllocatePool(EfiBootServicesData,
FileInfoSize, &FileInfo);
if(!EFI_ERROR(Status))
{
Status = RootFs->Read(RootFs, &FileInfoSize,
FileInfo);
Best Regards,
Aaron

Hi,
this sound somewhat trivial but I can't find a way to list the files of a
directory.
the EFI_FILE_PROTOCOL just allows to open a (sub-) file/directory but not
to get a list of all child nodes.
Michael
