If you’re using a Mac to connect to UUA network shares you may have noticed when you click on a folder with lots of items in it nothing happens for a minute or two. This has annoyed me enough that I actually switched to a Finder replacement (muCommander) for a while. (Finder is the Mac file management program that corresponds to Windows Explorer on Windows machines.) That worked pretty well but a recent conversation with a coworker lead me to another solution. The reason Finder takes so long to open a network share is that it is creating a hidden file to keep track of all sorts of stuff (such as icon location, and folder view settings). Since I’d gladly give up these features for a snappy file share, I figured out how to keep it from building this hidden file:

  • Open Applications
  • Open the Utilities Folder
  • Launch Terminal
  • Type (or paste):

sudo defaults write com.apple.desktopservices DSDontWriteNetworkStores true

  • Press Enter
  • Enter your password
  • Reboot your Mac

Next time you connect to a UUA network share you should notice Finder shows you your files much faster. If you have a favorite Finder tweak let us know in the comments.
