Create/Delete Mount Points

Hi,

Here is my problem…

How to create/delete volume mount points from
storage filter driver for Win2K?

I tried with IOCTL_MOUNTMGR_CREATE_POINT.
This is pretty working for assigning drive letters. But no idea
whether it works for creating volume mount points also.

Are there any other IOCTLs to perform this operation?

Thanks in advance,
Raju.

Volume mount points are created using FSCTL_SET_REPARSE_POINT.

Ralf,
Thanks a lot for your quick reply.

Volume mount points are created using FSCTL_SET_REPARSE_POINT.
Can i use this FSCTL from storage filter driver which is layered
below file system drivers?

Regards,
Raju.

First of all, there is a “suggested link name” facility, you can
employ it.
Second - write an auxiliary user app.

I can't tell you, sorry. But I have to agree with Maxim, creating mount
points and drive letters should be done from an user mode application.
