Unfortunately, there's nothing that the backend can
really do in the current implementation. The 4GB
limitation is in the FAT32 filesystem itself
(according to Microsoft's documentation).
About all the backend could do is try to split the
file up, but that adds a lot of overhead and
bookkeeping. However, seeing as there are many Linux
native filesystems that support files larger than 4GB,
I doubt that the developers would be interested in
trying to fix this.
I won't tell you that FAT32 is unsupported (because
that's not true), but it is bad and naughty. :)
There are a few ext2 drivers available for Windows,
some free, some commercial.
