thanks for the reply but unless i'm missing something, I can't see how that will enable me to change multiple specific folder/file permissions at the same time. The Security tab is only present when editing the permissions of single items...unlike XP where I can highlight as much as I'd like then set specific access control permissions to different users at the same time.
I have tried removing any read-only attributes but the Security tab fails to appear for multiple items...even though all my hard drive partitions and all their contents are 'owned' by me. The same applies at the root of any partition...but as far as I can tell inherited permissions are still being applied.
Apologies if I have missed something...it's kinda late and i should be getting to bed...have attached a couple of screenshots to show you what I mean.
This image shows no Security tab on the Properties menu when I select multiple folders..note the cleared read-only check box:
This picture shows the Security tab is present from Properties when only one folder is selected:
Thanks again for replying
p.s - I'm not worried about any access denied errors from the OS partition as they were easy to solve by booting into XP and setting the owner to administrators and applying permissions to those files while Vista was not loaded. There are lots of folders and files on my PC which I would like to restrict access to my daughter to as she would happily cause mayhem if she could run certain scripts and backup files. Unfortunately, i'm unable to do those tasks from XP due to the SID's.
