Changing IE default access directory

[jindal]

Hello everybody

my problem is related to internet explorer.
By default internet explorer can access my computer and all drive to
save, download, open files. i want to restrict this access to
particular directory "c:\internet" so that IE can access files system
below this directory. It should not able to access the file system
above this directory..

Can v do it with the help of Browser Helper Object...

Plz reply soon

Thanks in advance
