Did you had a look at _lseeki64?
An i64 should be sufficiently large even for 4GB+ files.

You can also use SetFilePointer or SetFilePointerEx http://msdn.microsoft.com/library/en-us/fileio/base/setfilepointer.asp

From my own experience I can say that it would be best to write a class/package/unit to handle the 64-bit file access. Microsoft's 64-bit API contains a wealth of functions, which use a trickier syntax than their 32-bit counterparts, but they need to be used consistently, otherwise very hard-to-trace errors can occur.
