[R] ffsave.image() error with large objects

Hi, I have been using ffsave.image() to save mixture of ff and normal
objects in my workspace. e.g.

ffsave.image(file = "C:\output\saveobjects", rootpath =
"D:\fftempdir", safe = TRUE)

It works fine but once my workspace has large (~4GB) objects, I get the error:

Error in ffsave.image(file = "C:\output\savedobjects", rootpath =
"D:\fftempdir", safe = TRUE) : ff image could not be renamed and is
left in C:\output\savedobjects

Could this due to the zip.exe having problem zipping a large ff object?

OS: Windows XP
DiskFormat: NTFS
zip.exe from RTool.exe

Thanks for help.
