How do I protect my documents from other people?

Question

I need to make my files secure. My PC only has one user account, everyone in the household needs it, but I've got my personal documents, I'd like to make them accessible only by me. How do I do this?

I don't want to create a password for my account and I don't want to create another user account: if I have to in order to protect my files, instruct me on the way to do this.

Thanks!!!!!!!!!

Answer 1

Use TrueCrypt to create an encrypted volume and store your documents there.

Answer 2

I am assuming you r using Win XP. Go to control panel. Double click user accounts and double click your user name (default is administrator) and select a password. From user accounts option u can also create new accounts and make new or old user account private.
Without creating password if you want to secure your folder then you have install third party software which is downloadable from internet and possibly you will get it free.
