It would work iff Windows would let you copy open files...

Apparently, there are some tricks to do this: MS Word appears to be able
to read file which are currently under work.

One possibility would be to use whatever trick is necessary
to read and copy an opened file.

Another one: tell Zope to pack its database (you can do this
via an HTTP request, e.g. with Python's "urllib" or with
"ZPublisher.Client"). When packing is complete, backup
"Data.fs.old".

There is a "PartitionedStorage" (or similar) around.
It allows you to partition a "FileStorage" over several files.

However, I do not know whether it allows you to do what you want.
And I do not understand why you want it...
