Thanks. Looking at Windows docs there is a GetFileSizeEx and maybe that'll make this 2.5GB file work on 32bit. Have filed here :

But the best we can hope for on 32bit is 4GB support, iiuc, using memory mapping which fread relies on. Quite possible that the real limit is around 3.2GB (whether RAM addressability limits apply to mapping files as well or not on Windows I don't know). I'll let you know when it's in v1.8.9 and you can try again.
If this quick fix doesn't work, then I'm not planning on trying harder. As the error message says: 64bit is the way forward.
