Hide Files is a program for the Mac that simply protects documents and folders from others viewing, modifying, or most importantly deleting.
It's as easy as dragging the file or folder into the app and clicking Hide, instantly those files/folders and all their contents are concealed.
There are options to enable password protection of hiding and unhiding these files/folders which ultimately hides them from gaining access to seeing them at all.
Just think, no more worrying about others finding your important documents, or your "special" photos!
A special note, this is a standard and simple way to make files/folders on the Mac operating system invisible. If you need advanced levels of protecting your data, there are many other ways to accomplish this including Mac OS X FileVault and various other removable media types.
