Recommended OTF Encryption Software for Flash Drives

Hi

I have just recently acquired a flash-drive and have been curious as to how to encrypt some files on it. The key word being some.

It's a large drive (8GB), and will be used for many different things. I want an area on the drive to be used to transport/hold personal documents which I wish to have encrypted.

I have tried software like TrueCrypt which decided to use the whole drive, and didn't seem to work properly anyway (?)

I want something that acts like a 'safe', I double click it, I enter a password, I access the files.

I need the software to run strictly from the stick, without the need for Admin' Privileges and for it to work on most operating systems (2000 and newer)...

I understand I could use old fashioned password protected/encrypted .zip's.... but I don't know if Windows can natively read these without the need of say 7zip or WinZip.

Can anyone think of something that fits my requirements?

Thanks

I use Truecrypt and it has always worked well for me.
With it you can create any size encrypted area on the drive that you would like and the Truecrypt application remains on the drive with it if you want.

I'm not sure what went wrong when you tried to use it.
