How do I re-hide folders?

Hi Teke0884,

This should help you with the hidden files on finder.

Paste this on Terminal and hit "Return"

Hide: defaults write com.apple.finder AppleShowAllFiles NO

Unhide: defaults write com.apple.Finder AppleShowAllFiles YES

Relaunch the Finder by Holding "Alt or Option" and click Relaunch.

Cheers

Enable Finder to Show Invisible Files and Folders

Open the Terminal application in your Utilities folder. At the prompt enter or paste the following command line then press RETURN.

defaults write com.apple.finder AppleShowAllFiles TRUE

killall Finder

To turn off the display of invisible files and folders enter or paste the following command line and press RETURN.

defaults write com.apple.finder AppleShowAllFiles FALSE

killall Finder

Alternatively you can use one of the numerous third-party utilities such as TinkerTool or ShowHideInvisibleFiles - VersionTracker or MacUpdate.

Use the following Terminal command:

defaults write com.apple.finder AppleShowAllFiles 0

Then I don't know what to suggest. There is no practical way to change the settings on every file on the computer. Something you have done has "fixed" this state such that the OS cannot undo it.

What you might try is using the TRUE option to reset all files to be visible, then reset to FALSE, and see if that will fake the OS into fixing it for you.

Needs the semi-colon.

defaults write com.apple.finder AppleShowAllFiles -bool true ; killall Finder

defaults write com.apple.finder AppleShowAllFiles -bool false ; killall Finder

I've also tried the other commands but this variation did the job for me running 10.10.3

defaults write com.apple.finder AppleShowAllFiles 0 ; killall Finder

This worked for me:

defaults write com.apple.finder AppleShowAllFiles -boolean false ; killall Finder

This worked perfect for me. I simply copy and pasted exactly what MattW214 said worked for him into terminal and right away it worked. (kindof scared me for few seconds when all my folders disappeared but they all came back but without the un needed hidden files. Thank you Everyone.

This worked!! Thanks much:)

Thanks, Matt! Worked perfectly!

Thanks MattW214 - worked perfectly for me as well!

Niel, if that truly is your given title of station, you are a god amongst men.

MattW214 thanks for the help. I did a copy and paste and it work. By reversing the command to show all of the hidden system files I finally got rid of that .DS_Store file that pops up everywhere.

After trying all of the terminal commands to no avail, I ended up deleting the com.apple.finder plist file in /Library/Preferences. After that, I relaunched Finder from the Force Quit menu. It created a new com.apple.finder plist file which contained all of the default settings. The hidden files were hidden again.
Caution: If you do this you may erase any other custom finder settings you previously created. In this case there were not any other settings I was concerned about.
