+  Convert a VIRTIO_FS_FUSE_DIRENTPLUS_RESPONSE filename to an EFI_FILE_INFO
+  filename.
+
+  @param[in] FuseDirent    The VIRTIO_FS_FUSE_DIRENTPLUS_RESPONSE object to
+                           convert the filename byte array from. The caller is
+                           responsible for ensuring that FuseDirent->Namelen
+                           describe valid storage.
+
+  @param[in,out] FileInfo  The EFI_FILE_INFO structure to modify. On input, the
+                           caller is responsible for setting FileInfo->Size
+                           according to the allocated size. On successful
+                           return, FileInfo->Size is reduced to reflect the
+                           filename converted into FileInfo->FileName.
+                           FileInfo->FileName is set from the filename byte
+                           array that directly follows the FuseDirent header
+                           object. Fields other than FileInfo->Size and
+                           FileInfo->FileName are not modified.
+
+  @retval EFI_SUCCESS            Conversion successful.
+
+  @retval EFI_INVALID_PARAMETER  VIRTIO_FS_FUSE_DIRENTPLUS_RESPONSE_SIZE()
+                                 returns zero for FuseDirent->Namelen.
+
+  @retval EFI_BUFFER_TOO_SMALL   On input, FileInfo->Size does not provide
+                                 enough room for converting the filename byte
+                                 array from FuseDirent.
+
+  @retval EFI_UNSUPPORTED        The FuseDirent filename byte array contains a
+                                 byte that falls outside of the printable ASCII
+                                 range, or is a forward slash or a backslash.
