Good password lock folder program?

[WBFAir]

Hello all

Did a search for this (probably a poor one) but didn't really come up with exactly what I was looking for.

I've finally gotten around to adding a card to my TP2 and now with real memory space I have uploaded a lot of stuff to it, but I would also like to upload all my work documents to it too.

But some of them are pretty sensitive if they were to fall into the wrong hands like if the phone got stolen or lost or something.

So I was wondering if there were any good programs out there that might password lock a folder?

It doesn't have to hide it, in fact I wouldn't want it too else it would be just that much harder for me to find.

I just want it require a password for accessing the folder and then allow normal access to any files in it after that.

I guess it would also have to not allow any files in that folder to be opened from some type of previously opened or find it in this folder thing of a program such as Word or Adobe

Thanks for any help
