How to get the Loaded file systems......

OSR_Community_UserOSR_Community_User Member Posts: 110,217
Hi,
I have a Filter Driver which needs to intercept all mount operations
of disk drives. I registered a driver routine to intercept all file system
registration. But how to get those file systems, which are already
registered, before my driver comes into picture? Anybody knows any APIs
for getting the registered file system??
regards,

    The best way to deal with this problem for now is to have your file system
    filter load at "boot" time. Boot time filters are loaded before any file
    systems (including the file system you are booting from). Note that the RAW
    file systems are loaded before boot file system filters. If you care about
    them you can attach to the RAW file systems manually when your filter loads.

    We are aware of this problem and it will be fixed in a future release of NT.
