Viewing hidden files in OS X
Mon, 22 October 2007
Unfortunately Finder has no option to show hidden files. But if you open the Terminal and ask your computer nicely - it will display the hidden files. This is how you do it.
Open ~/Applications/Utilities/Terminal and type the following:
defaults write com.apple.finder AppleShowAllFiles -bool true
and press return. Then restart the Finder by either typing
killall Finder
and pressing return, or hold down Ctrl+Option while clicking on Finder icon in the Dock and select Relaunch.

To disable displaying the hidden files, just repeat the process above, only replace the word true with false.

I’m sure you heard of TinkerTool. That tool does show hidden files plus do a whole lot more with a mouse click.

But of course, if you’re a serious computer user, you’ll be using Xfile. ;)

Rather than Xfile, I would suggest PathFinder. It’s free, and it’s more Mac-like than XFile, although XFile seems to handle perhaps more file systems. I don’t really care about the latter…
