[ Post being edited, Turned out to be far longer then I thought it would be ]

Due to my post being about 1070 Words long and needing formatting this forum doesn't have I had to make my post an article on my web site at http://www.techoddity.com/tobe.....ting-files

From your reply, it appears you already saw it or part of it and to answer your question, yes you could change the security settings of the file so only you have access though Administrators have the rights to change any security settings on a file so any other users with Administrator access could still change the security settings and access the file.
Also unless you have a BIOS password, anyone can boot from a Windows PE/Linux boot disc and have Administrator access to the whole hard drive.
And unless you change the password of the user account named "Administrator" then anyone can boot into Safe Mode and log in with the user account "Administrator" without a password and have Administrator access to the whole hard drive then too.

If you google "Vista file password", you will get a lot of options.

I am looking too, Gman, but so far the least expensive one I have found that will strictly password any number of folders is $40. Still looking for a free one. I am using My Lockbox as a stopgap, but I would rather be able to just up and lock any folder that suits me.

That one looks promising, but it is still $30 for a single license.

i doubt it. its probably a trial.

For text files, I would recommend Axcrypt.
Its free and has been around quite a while.

If you need something to encrypt more types of things, I like Truecrypt.
Its free as well.

Microsoft Private Folder comes highly recommended though I haven't used it myself - it creates a password protected documents area - it runs on XP only.
