Just to test, i grabbed a 256GB memorystick, made a separate partition, one 32gb and one 224ish gb partition.
Into partition 32 i put Portable software, windows managing, image viewers, Gimp, video editor, virus cleaners, useful tools and name it TOOLS, including VeraCrypt put aside.
With VeraCrypt i made the 224gb partition hidden.
Then i madean X amount of GB outer shell, also hidden with a PW, several important looking files. This partition is hidden when looking with windows file browser, so you can be forced to give one PW its this one you want to give, but inside this one hides 180gb very hidden partition, where i can stashe porn or other important files.
Very easy, even for me. Gonna be interesting to see reliability, how well the stick works, say going to visit my mother, clean her computer with ccleaner and whatnot scanners.
So now i have an USB stick with several good tools, and if i ever need a quick polish the spear i can just open VeraCrypt and do whats necessary. But yes i have all the same files backed up on another harddrive
