inVIZible is a new Mac-only application developed by MacHouse. What it does is simple. inVIZible lets you drag and drop files one by one onto the application and then organize/manage them.
Why do you need inVIZible? (1) You may want to hide important files from others who share the same computer with you. That's where inVIZible comes in. (2) You can use different applications to make files/foldres visible and invisible. Wish that you won't forget the location of an important file that you have made invisible. Or use inVIZible to keep track of all invisible files. Even after you once closing the application, inVIZible remembers which ones are visible and which ones are invisible.
