    I want to create/find a small app that will allow me to password a folder and all its contents.
    It has to work on PC and Mac.
    I've tried coding a few different idea but run into problems with the cross platform requirement or space on the drive.

    Anyone have any suggestions?

    I am rather fond of truecrypt. You can find a tutorial on how to encrypt a usb drive here: http://www.landofjacks.com/forum/viewtopic.php?f=3&t=13

    It will work on windows, mac and linux and wont take up any space on your drive. You will, however, need to have truecrypt installed on the computer you are using if you want to decrypt the drive.

    That's a major problem, I was looking into truecrypt and thinking maybe a partitioned USB drive, supposedly Windows doesn't like that a whole lot.

    You could use something like Winzip to zip and encrypt the entire folder into a single, password protected, zip file.

    I hadn't heard that before. My flash drive has a encrypted partition for my personal files, but also a unencrypted partition where I keep my "reward if found" file.

    What sort of problems does windows give you with partitioned drives?

    Was thinking about that as well.
    But then I started thinking about space on the drive, for that to work you'd need enough space to the original files and the zipped file.

    Don't know, I read somewhere that Windows doesn't like it.

    From the TrueCrypt FAQ:
    How can I use TrueCrypt on a USB flash drive?

    You have two options:

    Encrypt the entire USB flash drive. However, you will not be able run TrueCrypt from the USB flash drive.
    Note: Windows does not support multiple partitions on USB flash drives.

    Create a TrueCrypt file container on the USB flash drive (for information on how to do so, see the chapter Beginner's Tutorial, in the TrueCrypt User Guide). If you leave enough space on the USB flash drive (choose an appropriate size for the TrueCrypt container), you will also be able to store TrueCrypt on the USB flash drive (along with the container – not in the container) and you will be able to run TrueCrypt from the USB flash drive (see also the chapter Portable Mode in the TrueCrypt User Guide).
