I am running XP Pro in NTFS. I have the computer set up for mulitiple users, myself of course the administator. I have been messing around trying to block certain folders so only I have access to them. So far I have found that the only folders I can block are the ones in C:\Documents and Settings\Myname. Is that all I can block? For example, let's say I want to block a particular folder on another drive so no one but me can open it. Seems I can't do that. If I right click on the particular folder and go to properties/sharing, the 'make this folder private' is greyed out. It's only not greyed out on folders in the C:\documents and settings\myname folder. I am trying to make sense of the security stuff. Seems like it's rather worthless if I can only block what's in my documents and settings folder. I mean another user would not have access to that anyway because it wouldn't even be seen on another user's account. What am I not understanding here?
