GFUNK @QUASIMODO I don't think you're aware of the way unix works exactly. All "hidden" files begin with a period. You do not need Houdini to see "hidden" files it is just a way to look at the various directories with a GUI. you can open Terminal and go to the directory you want type the command ls -a ls is your list files and then -a is your option to show "hidden" files also. Remember unix is case sensitive so -a & -A are two different things. you can also go into Terminal and type this command which will allow you to see all hidden files from within the Finder:
defaults write com.apple.finder AppleShowAllFiles TRUE
then type the next command to restart the Finder so your change will take effect
Now you will be able to see all hidden files from within the Finder, you will know which directories are hidden as they will all begin with a period. This will stay this way even if you log out or what not so you will have to retype the command again to change back to default. For you to go back to default run the same command above just replace TRUE with the word FALSE, remember everything is case sensitive and must be typed exactly letter for letter. Hope this helps you out, and really if you run these commands you do not even need Houdini you can just use Terminal. Also you do not have to retype the commands each time you need to use it if you do not want to. Just open terminal and hit the up arrow on your keyboard and that will toggle through your previous commands issued. just keep hitting up until you find the text you want. Alrighty well good luck and hope this helps you out.
