you cant do it natively, but you can probably get 3rd party apps to do it

the easiest/securest way to do it, is to create a sparse diskimage which creates a .dmg file, encrypts it with AES 128 and assigns a password, i pretty much keep all my shit (thats worth stealing) in one of these files

open up disk utility, and select 'new image' .. set the type as a sparseimage, and its all pretty straight forward from there

ill post up some exact instructions when i get home tonight (where my ibook is)

you can also use stuffit to zip or .sit the file so that it cant be expanded without a password....

^ zip file passwords can be broken, im pretty sure AES128 can't be broken at all .. i think you would have to re-create the .sit file also if you want to keep adding stuff to it, using a sparseimage .dmg file its just like another folder/drive, you mount/unmount it and it grows as you add/remove shit

yeah you are right about recreating the .sit file.... but i mean i dont know if he is trying to archive stuff or just a folder you can keep gettin access too...i dont know how secure some of these things are tho....but it looks like going with the .dmg is the way to go if you can use it like an expanding folder.
