Please describe the purpose of EFI_FV_FILETYPE_FFS_PAD.
A pad file is an FFS-defined file type that is used to pad the location of the file that follows it in the storage file. The normal state of any valid (not deleted or invalidated) file is that both its header and data are valid. This status is indicated using the State bits with State = 00000111b . Pad files differ from all other types of files in that any pad file in this state must not have any data written into the data space. It is essentially a file filled with free space.
