ok i ahve played with ceedo, and Prayaya v3, but is there a cheaper way to make a flash drive that will run on virtualy any computer (at least vista installed on it), and not take more then 500mb of space as i'm using an 8gig flash drive and the app i wanna put on i take up almost 6 gigs!
No, it is a software for using virtual flash drives. And they are encrypted, too. I use it already ...
