I want to know if it’s possible to re-direct file I/O requests to another place.
For an instance, when explorer.exe browses on drive E (a CD-Writer drive), my driver builds new IRP(s) and sends requests to drive C (a local hard disk).
I have made it on Win9x and want to do this on 2K/XP.
In fact, this idea is from the CD-Buring function of WinXP. When files are copied to a CD-Writer, Windows puts these files to a ‘cache’ folder (named CD Burning). Then, Windows will ‘often’ prompts user to burn these files to a ‘real’ CD. Before user burns files, these files are visible, accesible when explorer or any other applications visit this CD-ROM drive.
Here, any one has finished this? Could you pls give me any hints? Thanks!
I recently asked some of these same questions on this
list. So if you search you will find more detail.
You have (at least) three tasks:
Manipulate
IRP_MJ_DIRECTORY_CONTROL/IRP_MN_QUERY_DIRECTORY irps
so that the files appear where you want them to
Redirect IRP_MJ_CREATE irps by using STATUS_REPARSE
Fail FastIoQueryOpen requests for files that you are
redirecting
