How to show the hidden files if not showing normally?

Hello,
Friends, I use Windows XP Sp 3. I have some private files on my PC hard disk. I use to hide them by just picking a tick on their properties window (in the hidden tick box). Recently I am having a great problem that my has hidden files are not showing while it is enabled from the folder option menu.
Every time when I am making it enabled on the folder option menu, it is becoming disabled automatically. It is really an unexpected situation for a PC user. I didn’t see this at first. To make this enabled, first of all I have restarted the PC. But I got the same situation. Then, I tried by the “files and folder search” menu. Again I got a failure. Then I have typed the path / directory address of my private files and pressed enter.
This time I have got my files. But, Opening these files from the run menu safe for me as run menu saves every path or address in its recently typed list. So, my folder option needs to be normal as past.
Is there any other way to make it Okay? I will be very pleased.
Thank you for reading this.
