The *specification* ([1], page 23, field DIR_FileSize) says that the filesize is 4-bytes in size, and holds a DWORD. Page 16 indicates that a DWORD is a '32-bit unsigned' (sic).
I assume that some *implementations* incorrectly make this a 32-bit *signed* integer, restricting the size to 2G maximum.
