While accessing my #webOS device, there comes a time when I need to show hidden files. But you can't find anywhere in the menu, just like you did with Folder Properties in Windows operating system. All you have to do is simple, using Terminal apps. Here's what you have to do:

1. Open Terminal apps
2. Type this command:

$ defaults write com.apple.finder AppleShowAllFiles TRUE
$ killall Finder

And suddenly you'll find changes in your Finder. If you ever want to get the already-revealed hidden files to default, just type the same command as above and change TRUE to FALSE:

$ defaults write com.apple.finder AppleShowAllFiles FALSE
$ killall Finder
