People often store their private data, such as passwords, photos and other on USB flash devices. If the device is given to someone, you have no control over your data. He may read and delete them, or even corrupt. For example, if a hacker have seen the password to your website, he'll probably try to hack it.
With a new tool, HideFlash 1.1, protecting your folders and files on USB flash drives become easy. For example, you create a folder, named "private" on the flash drive, run HideFlash and tell it to hide the folder. It makes all work, and now the folder is not visible! If you try to use your flash drive on another computer, the folders and files will remain invisible too. Even under Linux and MacOSx machines.
