Small Win32 C++ library with full source. Superfile is a class that encapsulates big 'virtual' files. It emulates a really big file, but only parts of it are actually written to disk (only the parts used) Superfile spans multiple filesystem-files. Maybe u could see it a little bit like a swapped memoryblock. It is made for Win32 with or without MFC. Currently a not-so-debugged version 0.1.
