Updatable Archive systems...

[manux]

Hello all,

I was looking at python's zipfile and tarfile libs, and I noticed the following:
-There is no real way of updating a file without re-building another archive since any new file, even if it's name is already in use, is just appended at the end of the archive.

So, is there a way to program an updatable archive?

I would like to create one in either Python or C, or both(since it's easily mutable).

Any ideas welcome!

Edit:
Ok so here is the thing

I'd need a system that can archive plenty files into one, and possibly encrypt them, but I don't really care for now.
The problem is: systems such as zip, or tar, won't let you "update" a file. They will just append the new data at the end.

I wonder if systems exist(programmable in C++), such as a vfs,that can manage "updatable" archives of file.

Is it clearer now ?

I think your topic is so intimidating... that no one can even see clearly the question!

Oh my, I was just gonna mention one article on CodeProject but it got deleted. It was a very interesting thing.
