Finding Hidden QuickTime Files
There are two ways to access hidden QuickTime files; as long as you know where they reside you can use one of these methods to display them (or use Finder to list them afterwards). The first method is to use the Terminal.
In Applications > Utilities, open Terminal and type:
defaults write com.apple.finder AppleShowAllFiles -bool true
Tap enter to run this command, and then log out of your Mac and back in again. You can also use the Force Close Finder menu option (press SHIFT with the menu open) or simply type and enter:
You will then be able to find the hidden files, although they may not necessarily open in QuickTime. Viewed files that work, however, should be moved to a new location, as you will need to hide your full stop-prefixed folders again:
In the Terminal, enter:
defaults write com.apple.finder AppleShowAllFiles -bool false
Again, you will need to relaunch the Finder with either of the methods explained above.
