On a pc Windows based running XP you cannot create say one or two locked folders. As Gary eluded to, you would have to lock it all down by password protection and that would mean you would need to be the administrator of the pc. You would then have to set up access accounts for each additional user.
My suggestion would be to buy an external hard drive that you could plug in via USB, put your files on it and when you are done, unplug it and go hide it somewhere, then when you go to use it again, just plug it back in.

The other option could be to burn your files to a cd and do the same thing.
