Re[2]: Overwrite Issue when reparsing MS word to a different volume

If you find the problem is the rename and returning=20 STATUS_NOT_SAME_DEVICE does not convert it to a copy/delete, then yes,=20 you'll need to implement it yourself as a copy/delete. That status code=20 will indicate to the calling application that it should perform a=20 copy/delete but not all applications will do that.

Re[2]: Overwrite Issue when reparsing MS word to a different volume

Further investigation shows that MS word call to NtSetInformationFile fails when the rename target is not in the same volume with STATUS_NOT_SAME_DEVICE. But as I read in these threads : http://osronline.com/showThread.CFM?link=223560 http://www.osronline.com/showThread.cfm?link=205385 I do not receive any set_information IRP and NtSetInformationFile fails in user mode. So it seams to be very hard to make it work in kernel mode, unless we can predict the rename when the file is being opened and create the same file in the target volume and mark the original file for deletion!!! which does not seam to be a safe solution. As for user mode solutions the only choice seems to be hooking the user mode API and converting the rename to create&delete operation, as Maxim stated in above topics. I am going to implement the hook approach and see how it works. Any hint for me?
