Hi,
thank you for your reply.
I remember in some cases, years ago I used to save only a part of the file,
locking for the exact point where saving the differences. May be I don't
remember very well.
As far as writing any time the whole file, I don't think it's a proper
behaviour for a database. Think about any time the user updates a record, I
have to quickly save the changes, so... a lot of disk usage.
Mmm...
Maybe something that sounds like FileWrapper can help me?
Best Regards

You need to save the whole thing again.

Is it a problem, have you benchmarked it?
