Union File System

[Michele Preti]

Hi all,

i need a linux like union file system, and I'm really surprised that i can't find even one.

i find http://code.google.com/p/winunionfs/

but it really does not what it should, it just get a "read only" folder, and a "write" folder and join them, treating oddly deleted files.

I'm looking for a fs which i can give a list of folders (saying which read-only and which not) and get a new driver with all the files and subfolders

does it already exist ?

Dokan is in my opinion not ready for production use.
The kernel driver produces randomly blue screens (even if no dokan fs
is used at all)

thanks, this thing leaves me disappointed ... I thought to create myself the file system but if you say that is unstable not worth it.

Is there any other similar library to work with?

The only usermode lib I'm aware of is commercial:
http://www.eldos.com/cbfs/

But you can write a kernel mode (ring 0 driver).
Look for: Installable File System

Can you use this http://liquesce.codeplex.com/.

I think that fixing Dokan would be better than writing only kernel drivers.

Did you notice any possible reason for these crashes? Which systems? Special conditions like power saving, drives changes, plug/unplug, registration or any possible cause?
I notice that killing userspace can cause a crash inside kernel.

Hello Frediano,

Yes, but I think development of kernel driver is stopped/sleeping.

> Did you notice any possible reason for these crashes?

No

> Which systems?

Windows 7 SP1 x32

> Special conditions like power saving, drives changes,
> plug/unplug, registration or any possible cause?

Not at all. If so I would have reportet a bug.
Took me a while for discovering that dokan crashes my system.
