Hi everyone
I’m working on writing a fsrec for several filesystems.
How could I pass data from when I recognized the filesystem (IRP_MN_MOUNT_VOLUME) to the upcomming IRP_MN_LOAD_FILE_SYSTEM callback?
Hopefully this isn’t a too dumb question, I’m a newcomer to the IFSKit.
Thanks in advance
/Johan Bj?rk
Standard recognizers do not do this, so, maybe no way.

Johan,
I would like to know why you are planning on writing a recognizer? Is this for some custom file systems you are developing?
Recognizers were first implemented to save memory back in the days when machines did not have a lot of memory. There is not much of a need for them any more.
You may want to decide if it is really worth the dev and test effort to do this. It certainly is not a requirement by windows to have recognizers for 3rd party file systems.

Hi
I understand, I am writing a kind of interface for other filesystem drivers my company might develop. Allowing to dynamically load, configure, and mount raw files.
I was hoping on combining the filemounting and the recognizer part, to get a bit more familiar with the IFSKit before diving into the ‘real thing’.
When you say this it makes sense though, I think I will be able to skip the recognizer part.
Thanks!

How do the standard recognizer do this? If I understand correctly it’s able to load either the ntfs,fastfat or cdfs driver?

They do ZwLoadDriver and return some status code from mount, so it is
retried with the new driver.
