HideSwitch is designed to do one thing and it works very well, making it easy to turn on and off the showing of hidden files on your OSX installation. For those that frequently find themselves looking for hidden system files or other files that they have purposefully hidden, this is a very useful tool. Despite one drawback, it's much easier to use than the built-in system settings and Finder settings that have a lot more tiers involved when changing even something as easy as this.
The setup process is straightforward. You will download a file from the developer that provides an easy click and run program file. When you open it, a switch appears onscreen that you can then toggle on or off. Toggle on to show your hidden files. Toggle off to hide them. The switch is a menu tool, so you'll need to find somewhere to put it, which means you probably won't run it constantly because it uses up desktop space. A menu bar option would not only have been nice to have, it would also have made more sense for what this tool does.
But that aside, the Hide Switch interface is easy to use, provides the tools needed to get the job done, and had no bugs in any of our tests. There are plenty of other file management tools out there that will do this and much more, but if all you need is a tool to show/hide your hidden files, look no further than HideSwitch.
