I've read the thread so far, but I'm still confused. Why would it work
at all on FreeDOS then? Perhaps they support the API (only)? I don't
think they (even these days) support bigger than 2 GB files, even on
FAT32. I guess it silently fails, dunno. I wish somebody (FD kernel
dev) would take a look, esp. since what other (free) choice is there?
Win9x is rare these days, and I'm not sure even Win2k/WinXP support
large files. Maybe EDR-DOS (FAT+), who knows.

Sorry if this comment isn't very helpful, but I felt like I had to say
it.   :-(
