The WPD pack files (not to be confused with the WDB files), is like a mini archive that can hold a lot of files inside it. they come in .bin, .wpd, .wpk, .xgr, .xfv, .xwb, and .xwp file extensions.

Sometimes these files can also have a paired IMGB file which can contain header less DDS texture or image related data for all txbh files (SEDBtxb section only data), that are packed inside this archive file.
